I think he'll be brilliant if we can manage to get him. He's got everything needed in a midfielder - passing, aggression, awareness, ball carrying - as well as knowing the league already, and a few of the players from international duty then off the pitch seems like a good lad too.
Not to mention the fact he's been coached by Bielsa for a few years which can only stand him in good stead under Pep in terms of positioning on the pitch.
Not every signing needs to be from a big club and a statement one (see Zaba and Kompany for reference) for the player to be effective in what we need. He is a very good player now and under Pep's coaching, he'll excel to another level.
All supposedly at a bargain price? Get him in.
