Shkodran Mustafi collapsed in a heap for a brief moment before leaping up to complain about the challenge. Burnley’s Sam Vokes had caught his opponent with a stray arm and Arsenal’s new centre-half thought foul play was at work, pointing to a speck of blood on his forehead as compelling evidence.

At this point, it would be easy to describe the episode as a ‘Welcome to the Premier League’ moment for someone who has spent his senior career in Italy and Spain. The majority of players coming in to this helter-skelter environment do need time to get used to the extra aggression.
