First-half goals from Andrey Santos, Tyrique George and Estevao Willian helped the Blues into the quarter-finals, despite a chaotic second half in which Tolu Arokodare scored once and David Moller Wolfe scored twice for Wolves, with Chelsea's Jamie Gittens settling the tie. Returning striker Liam Delap, who came on to the pitch in the 60th minute after 10 weeks out, was sent off late on for two yellow cards. Chelsea had been 3-0 up at half-time but were forced to throw on regular starters Enzo Fernandez, Marc Cucurella, Pedro Neto and Moises Caicedo to see out the victory during a second-half wobble. Remarkably, Chelsea had been 2-0 up after just 15 minutes, immediately sparking Wolves fans' chants of "We want Fosun out" - directed at the Chinese owners - and "You're getting sacked in the morning" - directed at Pereira, with the club bottom of the league and winless. Errors, including a 30-yard backpass from Arokodare five minutes into the match, allowed Santos to find the corner with his shot for his first Chelsea goal. The second, a wonderful team goal, culminated in Gittens crossing for George to finish from close range. But the game swung on Pereira's substitutions, beginning in the 19th minute, bringing off experienced defender Matt Doherty for midfielder Rodrigo Gomes and Marshall Munetsi and Ladislav Krejci coming on in further half-time changes, after Willian lobbed goalkeeper Jose Sa just before the interval. Support returned when Hwang Hee-chan played in Arokodare to score immediately after half-time, and Wolfe then volleyed into the corner after Yerson Mosquera's long throw-in. It was a chaotic last 20 minutes for Chelsea, with Delap sent off, Gittens scoring a sensational volley to restore a two-goal advantage and Wolfe lobbing goalkeeper Filip Jorgensen just 60 seconds later to spark a nervy six minutes of added time. The Blues' reward is a quarter-final trip to League One Cardiff City, the only side from outside the Premier League to reach the last eight.

David Neres' free-kick into the box was headed home by Andre-Frank Zambo Anguissa from close range in the 69th minute as Antonio Conte's side took the lead. Leece had a chance to open the scoring after 57 minutes when Francesco Camarda stepped up from the spot but his penalty was well saved by Napoli goalkeeper Vanja Milinkovic-Savic. The Serb has saved five of the past nine penalties he has faced in Serie A. The result means Napoli move three points ahead of second-placed AC Milan. It was Napoli's first game since Kevin de Bruyne suffered a significant thigh injury which will rule him out for a lengthy period. The league headers host Como in their next league fixture on Saturday (17:00 GMT). Later on Tuesday, AC Milan played out a 1-1 draw with Atalanta as they moved third, level on points with second-placed Roma. Samuele Ricci's deflected strike from outside the box in the fourth minute put Milan in front. However, their lead was cancelled out by Ademola Lookman who fired into the roof of the net in the 35th minute as the home side drew for the seventh time in nine league matches.

Nathan Lowe, Kyle Wootton and Jack Diamond all found the net in the space of 16 first-half minutes to ensure County climbed from fourth place to sit two points clear at the summit. Defeat for Vale, meanwhile, leaves them in the relegation zone two points from safety. The visitors opened the scoring in the 13th minute, with Stoke loan striker Lowe nodding home from Tyler Onyango's cross for his second goal in as many games. Wootton's precise finish from the edge of the box doubled the Hatters' advantage 10 minutes later and took his league goal tally for the season to six. And things got even better for Dave Challinor's side shortly before the half-hour mark as Diamond muscled Jesse Debrah off the ball in the penalty area before calmly slotting past Joe Gauci. Ruari Paton's long-range free-kick clipped the crossbar just before half-time in a rare attack for the hosts. Stockport nearly added a fourth goal when Lowe, who was lucky to only receive a yellow card for an elbow on Marvin Johnson late in the opening period, struck a post in the second period.

Eze joined the Gunners in a deal worth £67m in the summer and his winner came from another trademark Arsenal set-piece. Declan Rice curled a free-kick into the area which was knocked down by centre-back Gabriel, then Eze acrobatically fired the ball into the corner of the net. Crystal Palace, who lost to AEK Larnaca in midweek, did threaten on occasion with Jean-Philippe Mateta battling against the solid Arsenal defence - but they did not trouble David Raya in goal. Arsenal nearly doubled their lead in the second half when Gabriel hit the crossbar with a header and Bukayo Saka went close with a curled effort from the edge of the penalty area. The win means Arsenal are now unbeaten in 10 matches in all competitions.

The England midfielder produced a defence-splitting through ball to tee up Kylian Mbappe for the 22nd-minute opener, before his 43rd-minute tap-in restored his side's lead, five minutes after Fermin Lopez had levelled. It was Bellingham's fourth goal in five appearances in the clash between the league's top two sides, with Xabi Alonso's men moving five points clear of Barcelona as the game ended with Pedri sent off and clashes on the touchline. Real lost all four Clasicos in all competitions last season, but from minute one set about breaching Barcelona's high defensive line. The hosts were awarded a penalty when Vinicius Jr went down inside the opening two minutes, but a video assistant referee (VAR) review determined the Real Madrid winger had kicked the leg of Lamine Yamal before he went down. Ten minutes after VAR had ruled out a stunning 25-yard Mbappe volley from the edge of the box for a marginal offside, Bellingham spun away from Pedri before sliding a pass through to the French striker to slot past Wojciech Szczesny. Madrid peppered Barca's third-choice goalkeeper with shots, but were caught out by a 38th-minute counter-attack that ended with Marcus Rashford squaring for Fermin to equalise. And more controversy followed as Hansi Flick's side went behind again before the break. Barcelona's players felt Real defender Dean Huijsen fouled Pau Cubarsi as he tried to clear Eder Militao's header across the face of goal, but Bellingham was left unmarked at the back post to score. Mbappe was denied a second when he converted from another offside position following a magical team move started by Vinicius and Bellingham having his effort stopped. The second half began with VAR intervening once again to award Los Blancos a debatable penalty when the ball inadvertently struck the hand of Eric Garcia as he slid in to challenge Bellingham and the rebound ricocheted back on to him. Szczesny, though, produced a fine one-handed stop to keep out Mbappe's spot-kick in the 52nd minute. Bellingham then tapped in from Brahim Diaz's low cross with 20 minutes remaining but, for a third time, Madrid were denied by an offside call. The visitors struggled to test Real keeper Thibaut Courtois and the match ended in chaos with clashes on the touchline between the rivals. Tempers flared after Pedri was shown a second yellow card for a lunge on Aurelien Tchouameni deep into injury-time.
