Personally I think we would get the best info regarding how ready he is to play with us, by actually having him here playing for us, not somewhere else. I can understand why we are uncertain whether or not he actually is good enough to play for us today, but if that's the case it just seems strange to pay 20m for him now, instead of just trying to sign him for free on a pre contract in 5 months. I mean, he is 22 in a week, not 18. Would have made a little more sense if we would have loaned him out to a La Liga club or something. Just my opinion:)
