Started last night for Spain and did his usual good job of controlling the tempo from deep and positioning himself well to block off counter attacks.. He's a bit of a Carrick clone in some ways although in terms of United, I suppose he might lack a bit of physical presence for a team that is already sorely lacking in that regard. He'd definitely be a decent option for us, though, if he was prepared to leave Spain (and we could beat his other suitors - Arteta is reportedly a big fan).
Amadou Onana would probably be my first choice - he has all the attributes to become a really good Premier League #6 and still only 22. If we are looking for a more budget-friendly option, Anton Stach might fit the bill - Newcastle are apparently interested and Hoffenheim are reportedly only asking for €15m.
