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.
