when was the last time a loaned player got a minute for the club when he came back?? Yes it was Saviola in 2006\07, who came back against Rijkaard's will.
looks like the club doesn't believe in loaning young players. any way, in Tello's case I say he has what it takes to be a great winger for the team and he has the confidence after all these minutes from Pep (mainly starting the Clasico), so he with Cuenca are so ready and if we have to get an extra striker for the team, only a classic CF (a Larsson) then we are fine with what we have up front.
