It was from Feb of this year apparently, I don't think it matters that much, he's pretty much said he's a Spurs fan that's not going to change is it. Not a deal breaker but it is a reason for opting for a player from a team who aren't domestic rivals... the trouble is I don't think we are the only side targeting right backs and fullbacks this summer.
From a quick glance there doesn't seem to be many to choose from: Sidibe(AS Monaco), Bellerin(Arsenal...so not much better), Henrichs(B Leverkusen), Fabinho(AS Monaco)
Not heard much about Henrichs but out of the four might be the one we have the most realistic chance of signing.
