I’d definitely go for him. Don’t think €10m a year is an obscene amount either. I’m not Sure if his trouble-making has been overstated either. Every time a player get’s into a dispute with their club, be it about money or whatever, they get this label. These people are shaping their careers. If fans think they are ‘not worth the trouble’ because they are negotiating a salary for themselves or generally know what they want from their career, that’s probably because we’re a bit spoilt and just demand players turn up to serve us.
We do need a midfielder, and picking one of his quality up for free, who is a bit flexible too (although I’ve heard on here that he ‘won’t’ play in front of the defence, whatever that means), makes sense to me.
