Calum Chambers was made up to beat Manchester United at Old Trafford in his first attempt.
The fullback, who was brought on in the second half to enable Arsene Wenger to ensure that Arsenal remained with 11 men after united targeted Hector Bellerin and tried to get him sent off, was solid in helping Arsenal get over the line and claim their first win up there in, well, too long.
Tweeting after the match, the youngster said
First game at Old Trafford! Nice to come away with a win
