Not that much, but they haven't been shy of flashing the cash last season:
11m on Kodija
12m on McCormack
12m on Hogan
Plus lot of other deals such as 9m on James Chester. Was definitely a case of trying to buy self out of the league.
He's recently changed agents and it's no secret that he's looking for a move away this summer. Not doubting his quality but I don't think he'd be the left back signing we need from the times I've seen him play, looks good going forward but I'd have concerns over the defensive side of his play.
