It's a tricky question... for one Bojan is already adapted plus he is Barca's own product; he has shown a lot of potential, especially when Rijkaard was the coach. He may not be as good a player as Keirrison (not yet), but in years to come he will progress. Pep is the man who knows how much opportunities Bojan will get.... I don't want to see him sitting on the bench throughout the whole season. That would impede his growth as a player, in that case it would be wiser loan him out and try to use Keirrision who hasn't yet played in La Liga, but from what I've seen at the moment he is at least one level higher than Bojan in terms of quality. I watch a lot of South American football and I can tell you that this is one of the hottest prospects currently in the market.
