PHOTO: Theo Walcott poses with Alexis Sanchez's #17 Arsenal shirt

An excited Arsenal star showed his happiness at the club securing new signing Alexis Sanchez.

Arsenal forward Theo Walcott has been watching on the sidelines for most of 2014 so far thanks to injury, and he has the look of a real fan of the club, delighted at their new signing.

Walcott was the first player to tweet in recognition of Sanchez's transfer being announced, posting 'What a signing!!!' on his Twitter feed.

A day later he was at the club's new shop, re-branded by kit manufacturer's Puma, and found time to pose with an 'Alexis 17' shirt his new teammate would wear next season.

Arsenal posted the picture on their club Instagram account: Theo #Walcott was at the newly refurbished #Armoury today. Look what shirt he pulled out. #sanchezsigns #afc #arsenal #coyg #redarmy

It's the closest Walcott will get for now, Sanchez has now gone on holiday to re-charge after his World Cup exploits and will only link up with his new teammates in late July.

When he does though, with the pacy Walcott working with him in attack and Mesut Ozil pulling the strings behind, expect fireworks!
