The pair of teenage midfielders are considered among Arsenal's best young talents.
Arsenal take on Hull City today in the FA Cup third round, in a repeat of the final from last year.
Of course Arsenal often use the cup competitions as an occasion to rest some of their regular first-teamers and blood in a few of the younger models. Usually that model is saved for the League Cup, but after their early absence this season, Arsene Wenger may be tempted to play some young Gunners this afternoon. Not to mention the busy festive season leaving some of their regulars in need of a week off.
But there was certainly some young faces training with Arsenal yesterday, including two outstanding central midfield talents.
Gedion Zelalem has been dubbed the 'next Fabregas' whilst Daniel Crowley has earned the moniker 'next Wilshere' because of their respective playing attributes.
Both are considered potential first-team players for the future and Arsenal fans will certainly hope they are given their chance to shine in the not so distant future.
