He knows this players are average at the best, and that he can't win even La Liga anymore.
Smart move for him, his last 4 years are destroyed by Barto and his signings.
This.
You need to be elite athlete,speed,strenght,endurance,agility to be on top as winger.
Trincao and Collado just don't have that.
He will end up like most of these players from Barca B, that are good with ball but does not have some wc ability.
