This will be one for the vaults potentially, but I wouldn't mind Winks at all.
Once you get past Allan and Doucoure, we don't have another centre mid at the club that I'd particularly want anywhere near the team. Winks hasn't been in good form for a while, but an on form Winks looks after the ball better than any centre mid we have with the arguable exception of the one game in 30 that Gomes turns up.
Couple of things on this - at some point, if we carry on our good form, teams are going to sit in and not let us break on them and at that point having someone who can pass the ball well may be something we need. Secondly, having a deep-lying midfielder like Winks (at his best) who can pass the ball and has vision to execute a pass may well be a good thing from the perspective of helping us transition up the pitch quickly at times.
If Benitez wants him, I would accept that he sees a tactical role for him and would be confident we'd see a better version of the player than the one we've seen at Spurs since Pochettino left. Benitez has credit in the bank on this front at the moment, given the tune he's getting out of the likes of Gray, Townsend etc
