The Arsenal squad, former Gunners and supporters around the world have united to show their support for Theo Walcott.

It was announced on Monday evening that the forward will be out for at least six months after he ruptured the anterior cruciate ligament of his left knee in Saturday's FA Cup victory against Tottenham.

We invited Arsenal fans to send their messages of support on Twitter using the hashtag #GetWellSoonTheo and were inundated with tweets from across the globe.
