Not sure if he'll be captain material but he's certainly as talented, if not more so, than Jack Wilshere. The difference between the two is Wenger believes in his kids, whilst we're relatively amateur at handling them. Ancelotti's isn't palming McEachran off to Bolton at 17 though like Wenger did.
Currently, Wilshere looks a better version of Joe Cole at the same age but with a (far) better footballing brain. Josh McEachran closer resembles Andres Iniesta (In playing style), and given time, he may very well reach the same level Iniesta is currently at. Like Wilshere, he also has a footballing brain despite his tender age.
No way, i'm amazed this is even a debate. Knee-jerk reaction from his recent performances. Fabregas at the same age pisses all over Wilshere right now, and that's no downer on Wilshere's ability, it's just Fabregas was that f'ing good!
