Last year we needed that.Fair enough but of course I disagree with you and we need him playing in front of a back three or four to break up play and drive forward imv
Now we have Lo Celso, who does pretty much everything a lot better than Sissoko.
Gio tackles, he is one of our best passers, and he's probably the 2nd best dribbler on the team behind Son.
Both of them need to play beside a holding midfielder who stays back and screens the back line. Neither are that type of player.
