That's your opinion, but Bale is the ultimate kick and rush player to me. Never rated him at Spurs and I don't rate him at Real. His gifts are physical, borne out of his strength, power and pace.
We would need to replace ADM if he was sold, because we would need someone to replicate his threat of pace in behind. Depay is not that kind of player to dribble at pace with the ball in the ilk of ADM, he's a different kind of threat. We simply don't have anyone else who can do what ADM does, and that's not even mentioning his uncanny ability to provide cutting edge, creativity
and assists even when he's having a stinker.
