Premier League talking points

Defeats by Aston Villa and Bayern Munich in their last two matches called Arsenal's backbone in to question but Mikel Arteta's side answered the doubters with a gritty 2-0 win at Wolves to show that their title challenge is not over yet. It was a dour affair and though the statistics might suggest that Arsenal had it easy, they had to grind it out, scoring late in each half to show a different side of themselves that might prove vital as the title race reaches its climax. Victory over Chelsea on Tuesday would give them a four-point lead over Manchester City and although Pep Guardiola's side would have two games in hand, Arsenal showed they are still very much up for the fight.
