By Leagues I meant English and Spanish, rest are a bigger gamble that we can't take right now as we have no back up.
I don't think that it took Fred a year to adjust, he just can't play in EPL, in the CL to style of play is very different, no one is pressing him and he can take his time.
From the same opera - look at Tadic, looks like one of the best players this year in the CL, but would you buy him?
The player I would go is Rodri, as many here wanted for the DM role, and the idea of Dani Ceballos sounds great too for example, but I'm sure there are many more options.
