Both mentioned players are certainly very talented, Herrera is more of a creative cm in a similar mould to Cleverley, only recently joined Bilbao so whilst he is extremely talented not really the type or player we need. De Marcos is more of a box to box midfielder he is creative but has the defensive abilities, again he has great potential and out of the two then De Marcos would be the better option imo.

I think we can forget about any Bilbao player to be honest. They rarely like to leave and even if they do, they go tot he Barcas or the Madrids. If there's a player worth breaking the back for, it's Thiago Alcantara.

so you think that no bilbao players will leave but the one of the most promising playmakers at arguably the best side sin the world would? i reckon bilbao would accept 25 mil for munain if we wanted him or 25 mil for martinez

As for the other two mentioned in the original post, I think we have a far better chance of signing them instead.
