That's arguably more mouth-watering a formation than our Modric - van der Vaart - Bale midfield from back in the day. But it belongs in the past. And so does Bale. He is a nostalgia piece now. On those wages and at his age? To Spurs!? Not going to happen. Bale earns more in a week at RM than we pay Kane, Eriksen, Son, Dele and Lucas Moura combined.
Man Utd or Bayern. RM will have to hope one of those is tempted as I cannot imagine any other club will be (unless RM subsidise his wages, which won't help with FFP and defeats the point of RM moving him on in the first place).
