After FA Cup shocks involving Wrexham and Macclesfield earlier this weekend, it looked as if the Gunners, who made 10 changes to their starting line-up, could be on the end of another when Colby Bishop put the Championship hosts ahead after three minutes. But Arsenal were only behind for five minutes before Christian Norgaard forced the ball in via Portsmouth's Andre Dozzell after a trademark Gunners corner to level. That goal settled the visitors down and they took the lead from another set-piece when Martinelli flicked Noni Madueke's corner into the net after 25 minutes. Maduke had a chance to add a third from the penalty spot after he was brought down by Zak Swanson but the England international dragged the ball wide. Martinelli, who also hit the post and missed a good chance in the first half, added a third after Gabriel Jesus played a low cross into the area following some quick thinking by Myles Lewis-Skelly and the Brazilian tapped in from close range. Martinelli grabbed his third from another Arsenal corner when the forward flicked the ball on from the near post and into the net. There was then a piece of history when at 16 years and 135 days defender Marli Salmon became the youngest player to feature for the Gunners in the FA Cup.

Inter went ahead in the ninth minute when Federico Dimarco latched on to Marcus Thuram's pass and fired home from an acute angle. Eljif Elmas played a ball into the path of McTominay, who burst into the box and scored at the near post to equalise for Napoli with 26 minutes played. The hosts went back in front in the 73rd minute when Hakan Calhanoglu's thunderous penalty went in off the post with goalkeeper Vanja Milinkovic-Savic diving the wrong way. Amir Rrahmani was judged to have caught Henrikh Mkhitaryan in the box - and Conte was dismissed for his angry reaction to the decision. However, Napoli drew level once more through McTominay's superb first-time finish into the bottom corner nine minutes from time. Inter are three points ahead of rivals Milan while Napoli move up to third, level on points with Roma. Cristian Chivu's side have the chance to increase their lead to six points when they host Lecee on Wednesday (19:45 GMT).

England striker Harry Kane took his league tally to 20 goals in 16 matches this season, bending a stunning right-footed strike into the far top corner to put his side 6-1 up. Wolfsburg set a Bundesliga record by scoring an own goal for a third consecutive game when Kilian Fischer diverted Luis Diaz's cut-back into his own net in the fifth minute. The visitors responded through Dzenan Pejcinovic's equaliser, but Bayern stormed back to take complete control. Diaz restored their advantage by heading in Michael Olise's cross for his ninth league goal of the season, before the French forward struck twice himself in the second half of his 50th Bundesliga match for Bayern. Olise curled home his first five minutes after half-time and added a second in the 76th minute. By then, a Moritz Jenz own goal and finishes from Raphael Guerreiro and Kane had already extended their commanding lead. Leon Goretzka added an eighth from a tight angle in the 88th minute as Vincent Kompany's side made the perfect start as the league resumed following its winter break. Second-placed Borussia Dortmund drew 3-3 at Eintracht Frankfurt on Friday night.

In front of his old boss Sir Alex Ferguson and with former team-mate Darren Fletcher in interim charge at his old club, Welbeck belted home Brighton's second to send them into the fourth round. It was the 35-year-old's eighth goal against United and his sixth visiting the stadium he used to call home. The thunderous drive into the roof of Senne Lammens' goal doubled a lead given to Brighton by Brajan Gruda's first-half opener. Benjamin Sesko's header five minutes from time breathed life into the home side but 18-year-old home substitute Shea Lacey was sent off in the final minute and Brighton held on for their first ever FA Cup victory against the 13-time winners at the seventh attempt. For United, this defeat followed up the embarrassing EFL Cup second-round exit at League Two Grimsby, meaning they had exited both domestic cup competitions at the earliest possible stage for the first time since 1981-82. It also means Fletcher's two-game stint as interim boss contributed a disappointing Premier League draw against Burnley and this home defeat to a campaign that is beginning to unravel. United have now won once in their last seven games, with title contenders Manchester City and Arsenal their next two opponents. Within the next 48 hours, the club are due to name who will replace Ruben Amorim until the end of the season, with Ole Gunnar Solskjaer and Michael Carrick viewed as the frontrunners.

After Omar Marmoush slotted the Pharaohs ahead after just four minutes, the North Africans were never behind in the game. But Emerse Fae's Elephants are known for their resilience and refused to let their opponents blow them away despite Ramy Rabia's header giving Egypt a 2-0 lead just after the half hour. Ahmed Fatouh's own goal gave the Ivorians hope before half-time, but Salah quickly restored a two-goal cushion for the record seven-time winners. Guela Doue's backheeled effort after 73 minutes set up a grandstand finish but there was to be no fairytale comeback for Ivory Coast this time around. The result means Salah's bid for a first continental crown with his country is still on course. He will now take his team to Tangier to face Senegal, who beat Egypt in the 2021 final, on Wednesday (17:00 GMT).
