That will be an overkill.Imagine Sissoko and Ndombele in the midfield, that would be unbeatable.
We need someone with good passing range to pair up with Sissoko, eg Andre Gomes.
We have seen how Ajax can press the hell out of us when we have 2 big players in Wanyama and Sissoko whose physical presence can’t compensate for their lack of mobility and passing ability.
A defensive pairing of Sissoko with Winks/Gomes can help bypass the high pressing that certain team employs.
