Arsenal’s 5-1 thrashing of West Ham last night was initially overshadowed by what looked like a very nasty injury to Hammers defender Dan Potts.

The 18-year-old full-back was involved in a horrible clash of heads with Arsenal’s Bacary Sagna, which left him motionless on the floor for 15 minutes.

The youngster was stretchered off the pitch and spent the night in hospital, but the early noises from West Ham suggest that Potts suffered nothing worse than concussion.

Let’s hope that’s the case and that he’s back in action soon.
