I think it will depend on how Boehly & co’s plan. If they want instant success, especially in Cups (Carabao, FA, Champions League or Europa): we should extend Kanté. He was our main key during UCL winning last year. But if they don’t care about this season or the next and think more about the future: we should let him go. With his injury, it’s difficult to predict how many games he can play. And because the system is built around him, when he’s not there like this season after the match against Spurs: we are in total shamble. No other player can play his position better than him, not even close.
My opinion: offer him 2 year with 1 year of extension depending on number of games he will play. Same salary. So we know that he won’t be present that much but it could ease up the transition and it could allow us to get some results when he’s not injured. And if PSG or other teams are interested in him: we can get some transfer fee. But if he refuses the term, we should just move on, let him go for free 2023.
