Slap a £77m price tag on his head and get a contract extension to his agent as soon as possible with a pay rise. I am not saying go offering him 150k a week as he's not worthy of that, but if he's not already then he should probably be our top earner, especially knowing that he'll leave as soon as our valuation is met anyway so we won't be paying him that for years on end.
I don't think he'll have any qualms in joining a different Premier League side, and nor should he, and I think Spurs would be a very attractive proposition to him.
Spurs do have a number of players I'd be interested in, but you just know that they'd be way overvalued and we'd come out of the deal looking like we've basically given him away for next to nothing. I can absolutely see a deal where we get Winks in exchange and any monies owed for Alli (don't forget the widely-quoted 'up to £40m' fee) written off. Winks and Alli for Richarlison anybody? lol
