Every coach got his own share of wrong acquisitiosn , but the way the young players are hammered in this forum day in day out is nauseating. FFS even mature players need time to adapt in their new club(remember Gareth Bale's first year?) but we are talking about young guys with lots of talent trying to integrate to clubs play-style being viciously attacked by this forum. Unfrigginbelievable...
There is a thin line between:
1. a young guy just needing time, and this is why he is crap/meh currently
2. and: a young is just a crap/meh and he will never reach Barca's level and this is why he is crap/meh currently
This is why you need to give some time to a new player to see whether he is just crap or he needs time to integrate into a team.
But also, on the other hand, you can't give an unlimited time to a new player. If a new guy plays meh for too much time that it is more likely that he is just not good enough for Barca than that he just needs time.
(Rakitic integrated after 3-4 Months, right? Suarez also)
Imo, 1 year is a fair amount of time to give to Denis and Gomes (and let's say Mats) to see how are they fitting.
But if they'll be as meh as they are today even in their 2nd season, then: so long boys and good luck in some other (probably weaker) club, and we'll try with someone new.
