Calum Chambers made his 50th appearance for Arsenal when he came on as a sub against Newcastle at the Emirates on Saturday but it seemed to catch him by surprise.

The Englishman replaced Olivier Giroud with 88 minutes on the clock as the boss flung on all his defenders in a bid to hold on to all three points and top spot in the Premier League.

After the game, which saw Arsenal extend their lead at the top from goal difference over Leicester to two points over Leicester and remain three ahead of Man City (who were dismal for 80 minutes against Watford but sparked to life for about two minutes in order to smash and grab the points), Calum took to Twitter to reveal that he didn’t even realise he’d played that many times.

Chambers arrived at Arsenal from Southampton in 2014 in a deal worth a reported £16m (inc add-ons). He was initially thrown straight into the side when injuries gave Wenger no other choice, but after a whirlwhind first six months, he has been used far more sparingly ever since.

He’s made 14 appearances in total this season, although only four have been starts as he is currently being refashioned into a defensive midfielder.
