We should buy him now and think about what to do with him later. Either bring him back or loan him to a team playing european football, don't loan him back to sassoulo again he has learned all he can learn playing at that level.
that isn't my point. Look at the success of the German NT in recent years they flourished having played together at u21 level in these tournaments rather than give them half a game in a pointless friendly match making the transition to the senior side much smoother with tournament and cup experience under their belt already.
Chemistry helps. Conte has mixed so many new & old players in the national team I think he is starting to realize that letting the youngsters gel together over time will benefit the NT.
