But his goalscoring performance against United put paid to claims he is a one-season wonder.
Former Sunderland striker Quinn believes Jose Mourinho should have signed Kante during the summer transfer window because his midfield was so flimsy in the Stamford Bridge mauling.
And Quinn describes Kante and Nemanja Matic as “pretty frightening guard dogs”, who run the show from midfield for Chelsea.
Discussing the 4-0 win, Quinn told Sky Sports: “But as [Antonio] Conte exorcised the last echo of a Portuguese accent from his office Kante gave a performance which suggested he is the midfielder Manchester United should have bought this summer.

“It wasn’t just that Kante was one of the dominant forces of the afternoon but his goal in the second half highlighted the fact that United are playing at the moment without any world class defensive presence in their midfield.
“By contrast Chelsea’s midfield is built around Kante and Nemanja Matic, two pretty frightening guard dogs.
“Kante is settling in and looking more like the player he was at Leicester last season.
“He has a bit to go before he matches Claude Makelele in the role but even the fact that people are talking in terms of comparisons shows what a good investment he has been.
“Kante’s energy and defensive ability has allowed Matic to show another side to his game. He gets forward now when there is the space to do so. He is less worried about being the last man back before the ball moves into [David] Luiz’s orbit.”
