Maybe I'm just a glass half full kind of guy but I don't think that was a dig.
I read it as if I work hard I can get a move to a top club like Arsenal but if I work even harder I can get an out of this world move to a dream club.
That says to me he wanted to come to Arsenal, but would prefer Barcelona, which sums up pretty much every player we've signed in the last 20 years.
Any player that isn't aiming for the top isn't worth having. It's our fault that we're not the top, not Barcelona's and not Arda Turan's.
