Arsenal shrugged off the disappointment of their Champions League exit to move back to the top of the Premier League with a 2-0 win at Wolves on Saturday.
Leandro Trossard and Martin Odegaard struck at the end of each half to take the Gunners one point clear of Manchester City, who have a game in hand.
Arsenal's season was in danger of coming completely off the rails after a three-game winless run.
