I still think the biggest deal-breaker will be Eriksen's willingness to come here. Throughout his career he has been clever in going to clubs, where he would be reasonably certain of being a starter and playing most games (perhaps with the exception of the Inter move, which didn't work out at first). Ajax, Spurs and Brentford all turned out to be great moves for him in terms of developing him as a player, and in the Brentford case getting him back to playing.
He clearly wants to be playing first team football, and with the World Cup coming up he will want to be match fit come November. Unless ETH can convince him of regular playing time, I don't see it happening.
