If he's available in the summer we should certainly consider him.
He won't put up with any lack of effort from the players
There is no way Conte is leaving in summer. Levy has not stood in the way and let players go in Jan, including Dele on a free with options. That happens only if Levy is 100% on board with Conte with view to backing him in summer.
The 2 Jan signings Bentancur & Kulusevski, who Conte wanted, have been hits. Even if Spurs dont get CL end of season, I can see Spurs improving the XI and Squad immensely next season. Conte is one of the highest paid manager - its not like Conte has to go to United to get paid. At United, he would inherit a a squad that he has to trim and reshape again. I am not saying Spurs have better squad - just saying he has already done most of the trimming & reshaping at Spurs - cant see him wasting another year to do the same things.
In Romero,Dier, Bentancur, Kane, Son - he seems to have the core of the team. Kulusevski also look super signing. All he needs now, is a LCB, right wing back and a CM who can dictate play.
As for as United, Ten Hag anyway will be better suited - will be more aligned to what Rangnick will want to do
