PHOTO: Joel Campbell finally in Arsenal colours, squad number revealed?

Joel Campbell has been pictured in Arsenal colours for the first time, and may have revealed his squad number for the coming season.

Costa Rica international Joel Campbell is making strides to finally join up with Arsenal.

He uploaded a photo of himself onto his Twitter account, wearing a Gunners training top - bearing the number 28.

Campbell is finally in North London, having returned to the club after an extended break from his participation at the World Cup. He was not back in time to travel on the club's pre-season trip to New York, and will instead hope to make his debut in the Emirates Cup in early August.

The number 28 shirt at Arsenal is currently vacant, after Kieran Gibbs gave it up this summer to take the number 3 shirt from the departed Bacary Sagna. While not confirmation, it is a huge hint, that this will be the number he takes this coming season if his place in the squad is confirmed.

Campbell has been out on loan for the past three seasons since signing for Arsenal, to Lorient in France, Real Betis in Spain, and Olympiakos in Greece, but as his message above shows, it is the Gunners he is 'focused' on.

With Theo Walcott still not fully recovered from injury, and German stars Lukas Podolski and Mesut Ozil due back late from breaks, there is a unique chance for Campbell to stake his claim for a role this coming season.

He appears determined to impress, and an instant impact in pre-season, will surely seal the deal for him to stay, despite interest from AC Milan in signing him this summer.
