A goal for Martin Odegaard on his North London derby debut and a contentious penalty from Alexandre Lacazette gave Arsenal a comeback win over Tottenham Hotspur at the Emirates Stadium. The away side took the lead against the run of play when Erik Lamela, on as a substitute following an early injury for Son Heung-min, scored a stunning rabona. Lamela was later sent off after picking up two yellow cards, while Odegaard and Lacazette gave Arsenal the lead at the other end. Lacazette acknowledged Arsenal had got lucky with the award of the spot kick, after initially missing his kick before falling under a challenge by Davinson Sanchez, although the decision was confirmed by a video review. Tottenham manager Jose Mourinho said: "We played really bad in the first half. The 1-1 was not a fair reflection of the first-half. We were poor. Defending bad. No intensity or pressing. Some important players hiding. Really bad." Arsenal manager Mikel Arteta tsaid: "We had a really strong performance right from the beginning, we created many chances and went a goal down with their first shot. But I love the reaction of the team, we stayed composed and in the end we won the game." Player ratings from the match can be seen in the picture gallery above.
