Barkley can only go back on loan to Wednesday, as he has already played for two clubs this season.
I think some people are expecting too much from him. He is being hyped up as the next Paul Gascoigne, whereas I see him as the next Leon Osman, which is a compliment and not an insult.
Osman didn't break through to Everton's first team until he was about 23, and I think it will take Barkley a similar period of time before he becomes good enough and reliable enough to be starting premier league games.
