If we're planning solely for this season, then no point doing it for big money. If we're planning for the next few seasons, we would need to go for him now, because other clubs will also be after him in the summer?
I don't actually think loads will be - or of the ones that will be, we'll be the best.
United may need a left-back, but there's doubts over Mourinho's future as it is and they'd most likely want a really big name for that position if so... It looks like Rose.
Spurs... Suppose they're a possibility should Rose leave, but Tierney would have to settle for second-fiddle and at this stage the lad knows he needs regular games.
L'Pool. Again, they have Robertson and Moreno. One of them would have to go and then it'd be between Tierney and whoever else (probably Robertson).
Arsenal. They have Kolasinac plus Monreal. Suppose it depends if they see it as a dire need in the summer.
City and Chelsea won't go for him.
So that really leaves us and the rest of the league. Leicester have Chilwell, even if Fuchs does leave. If we can cement ourselves as among the best of the rest again this term, I see no reason why we couldn't attract him in the summer. I just don't think he'll be leaving this window, and the fact Celtic are open to selling Dembele kind of proves that.
