Bale would be a massive signing. Unlike most other world class players who like attacking, he'd probably work quite well with Mourinho.
Going to Spurs would be massive for them. But even with a massive pay cut, someone still has to be the transfer fee. He's contracted till 2022. I can't see a way Spurs can realistically get him over the pond without trading for another star. (Kane to Madrid?)
I read an interesting rumour from a Redditor that Griezmann is still on the cards and Reddit has a weird way of picking this stuff.
