it's a big question whether he's washed up or not, he might have the same rennessaince Pirlo had when he joined Juve after a season on the sidelines, surely he has a lot to prove after that disaster in Barca where he didn't even get a decent chance.
however we're so bloated in midfield it's not even funny, can't we at least loan out Rabiot or Bentancur or Ramsey?
