With just seconds left, Brazil won possession back on the edge of the Japan box and Bruno Guimaraes slipped the ball into Martinelli, who took a touch before slotting in off the post. It was a heartbreaking end for Japan, who had more than matched Brazil in the first half and battled valiantly in the second, but Carlo Ancelotti's side kept pushing and got their reward in final moments. Japan were comfortable in the first half and Kaishu Sano pounced on Danilo's loose pass to drive past Casemiro and drill the ball into the bottom corner to give his side the lead. Brazil struggled to respond before half-time but looked a different side after the break with Casemiro rising to power home Gabriel's back-post cross 10 minutes after the restart. The goal had been coming and the five-time World Cup winners nearly took the lead in stunning fashion three minutes later. Vinicius Jr received the ball 10 yards inside the Japan half, nutmegged his marker, drove into the box, jinked past another defender and stabbed his shot towards the far corner - only for Japan keeper Zion Suzuki to tip it on to the post. Japan regrouped from there and while Brazil continued to push forward, chances were limited. That is until Ao Tanaka lost the ball on the corner of his own box and was ruthlessly punished by Martinelli and Brazil.

In a scrappy game short of clear-cut chances, and with extra time looming, Eustaquio provided a rare moment of quality with a superb low strike from the edge of the penalty area to give Canada the victory. Canada had lost all six of their World Cup matches before this tournament, but this victory continued a superb competition for them. They defeated Qatar 6-0 on 18 June for their first success in a finals and this was another special moment for Jesse Marsch's side as they became the first nation through to the last 16, where they will play either the Netherlands or Morocco in Houston on Saturday, 4 July. In a team huddle immediately after the final whistle, Marsch could be heard telling his players "you are Canadian heroes. The future of the sport in this country is huge because of you". South Africa had finished second in Group A, but produced a disappointing performance in Los Angeles, with only one shot on target and they looked happy to settle for extra time, before the decisive moment. Canada's Moise Bombito's header was cleared off the line by South Africa's Aubrey Modiba, before Marsch's side thought they should have had a penalty after a challenge from Khuliso Mudau on Richie Laryea. Marsch was incensed at the decision and tried to talk the officials at half-time, only to be stopped by Bombito. Only some superb defending from Mbekezeli Mbokazi denied Jonathan David a goal with a vital block, with Canada having further chances following the introduction of Bayern Munich full-back Alphonso Davies, with Jonathan David and Promise David both coming close. But Canada, who had seven shots on target, got the victory they deserved late on to progress and eliminate South Africa.

Having been left on the bench, with Argentina having already won Group J, Messi was brought on in the 60th minute to the loudest cheer of the night. That was until he curled a low free-kick around the wall to extend Argentina's lead with 10 minutes to go. The goal was Messi's sixth of the tournament already - putting him two clear of his nearest challengers in the race for the golden boot - and a record-extending 19th World Cup goal. It also meant the former Barcelona forward became the first man to score in seven consecutive World Cup games. "Simply incredible," ex-England midfielder Danny Murphy said on BBC One. "He just impacts games. "He's so clever, so bright. He's so aware of what's going on around him. It's an absolute pleasure to watch him do what he does." Earlier, former Tottenham midfielder Giovani lo Celso had opened the scoring for a much-changed Argentina team as he whipped a superb free-kick into the top corner. Striker Lautaro Martinez doubled the lead with an emphatic penalty thumped into the bottom corner, after the referee had been sent to the monitor to see Marcos Senesi had been inadvertently kicked in the head as he dived to head the ball at goal. While Argentina were in control, Jordan continued to fight and halved the deficit with a brilliantly worked goal 10 minutes into the second half. Having started the move, substitute Mousa Al Tamari was there to convert Ehsan Haddad's excellent ball across the face of goal. The stadium erupted a couple of minutes later when Messi was introduced for the last half hour. There was a buzz of excitement every time he got on the ball in the final third and he gave the fans at Dallas Stadium the moment they so craved with another record-breaking goal.

Austria - who led twice - were heading out when Riyad Mahrez scored his second of the game to put Algeria 3-2 ahead in the 93rd minute. At that stage, Iran were going through as one of the eight best third-placed teams. But then Sasa Kalajdzic headed a 96th-minute equaliser to secure a point in the Group J meeting that sparked dramatic scenes of celebration among the Austria contingent in Kansas City. In snatching that late draw, Austria became the first team to avoid defeat in a World Cup match having fallen behind after the 90-minute mark. Iran - who had seen a late winning goal disallowed for offside following a video assistant referee check in Saturday's 1-1 draw with Egypt in Group G - are out despite being unbeaten, having drawn all three of their matches. But even though Austria and Algeria went into this match knowing a draw would take them both through, there was no sense of a repeat of the 'Disgrace of Gijon'. In that infamous match at the 1982 World Cup in Spain, West Germany beat Austria 1-0 in a group match where both teams went through the motions. They had known that scoreline would put them both through at the expense of Algeria. But this match was played in the right spirit throughout, with the intensity only dropping off in the final few minutes before two goals in added-time. After finishing as Group J runners-up, Austria now face Spain in the last 32 in Los Angeles on Thursday (20:00 BST) while Algeria, who eliminated Iran to become the final third-placed finisher, will take on Switzerland in Vancouver at 04:00 BST on Friday. The game began with high intensity and pot-shots at both ends in the opening 10 minutes, though it petered out by the first half hydration break. However moments after the resumption, Marko Arnautovic raced on to David Alaba's ball over the top to control and scuff a shot past the flat-footed Oussama Benbot, picked in goal ahead of Luca Zidane. Facing the prospect of elimination, Algeria went on the front foot and Fares Chaibi thumped the post with a superb 20-yard effort before Rafik Belghali reacted quickest to a ball bouncing back into play off the corner flag to bundle into the box and jink some space before lashing high inside the near post with half-time looming. Austria restored their lead 10 minutes after the break as Marcel Sabitzer side-footed home first-time from Konrad Laimer's cut-back to the edge of the box. But within five minutes, Mahrez turned in at the far post after a fine run and cross from Houssem Aouar. Both sides came close to what would have been a winner before the intensity dialled down after the 85th minute. After boos had begun to rain down from the stands in the first of four minutes of added time, it ramped up again when Mahrez ended a period of continuous possession by lashing home an angled shot from the right of the box in the 93rd minute to put Algeria 3-2 up and on course to finish second. However just 61 seconds after coming off the bench, Kalajdzic headed home in the 96th minute - two more than was allotted - to snatch a draw in the most dramatic of finales.

The South Americans appeared to have won a thrilling game in the 90th minute when Davinson Sanchez headed home, but he was denied by the verdict of the assistant referee - having been offside by a fraction. Replays, broadcast in the stadium to hearty boos, showed the tip of the former Tottenham centre-back's right boot was offside when the cross was delivered for him to head past Diogo Costa. While it was offside by the letter of the law and did not affect the group standings, it denied Colombia a win they would have deserved on the balance of play and left a sour taste in the BBC studio. "It's onside, I don't care what they're telling me and what information they're giving me, that is onside," former England striker and BBC pundit Wayne Rooney said. "That cannot be offside. Imagine that goal was to decide if Colombia were in or out of the next round." Colombia manager Nestor Lorenzo meanwhile joked in his post-match media conference that he would ask Sanchez to visit a podologist before their next game.
