Would have to be under a manager other than Hodgson though. But yeah I think probably a 2 season loan would be beneficial for both clubs in the end. If Torres can stay uninjured and on-form as well he could be a role model for Bojan.
I really like Bojan and hopefully with some experience outside he can definitely be a future star for Barca.
It seems that you're so optimistic about this kid!
First, i did think that he's gonna be a real star, but after span of time, I do not think as same as before anymore.
He lacks body power; it's his first issue; Bojan should concentrate on improving his physical strength, if he's really determining to be a star.
Watch Messi, he has been never beaten in body against body fighting on the pitch, even against strong defenders who are bigger (physically) than him and i believe that it's why he is never loosing the ball.
it's exactly the same story about other stars such as Cristiano Ronaldo, Wayne Rooney and ... .
Remember Ronaldinho's case; Since he lost his physical strength, he wouldn't have been that good player anymore.
I can easily remember those scenes which at them, Bojan fall down easily and loose the ball in order to fight against defenders, then nothing at all...!
I think that it's his first issue; If he does not solve this, it'll be impossible to imagine him as a star. Remember that it's only one of those issues that this kid has, there are many more there!
Anyways, lets be optimistic about his case as you're now!
