Chelsea midfielder N’Golo Kante remains a significant doubt for Sunday’s massive Premier League clash against Manchester United.

The Frenchman is back in training after overcoming a hamstring injury picked up on international duty and has not featured for the club since Chelsea’s 1-0 loss to Manchester City in September.

Conte had previously hinted that Kante could return to action against Roma in Tuesday’s Champions League tie, but he was left out of the matchday squad for the trip to Rome.

He did, however, travel with the rest of the squad to the Italian capital, and The Independent report that Kante provided a brief update on his chances of taking on United.

When he came through the mixed zone after the match, he was asked if he would be ready for Sunday’s game, to which he signalled that his chances are only 50-50.

The former Leicester man is expected to be assessed over the coming days, with Conte prepared to make a very late decision on whether he will play.

When asked why Kante was not playing against Roma prior to kick-off in Tuesday’s game, Conte said: ‘Kante, obviously is the type of player who is very difficult to leave out.

‘He just felt he was not 100% and after a big injury I think it’s not right to push the player because the player must feel the right feeling and then to play, also because if he risks another injury, it’s a disaster for us.’

Chelsea succumbed to a 3-0 defeat against Roma in the absence of Kante, and have kept just one clean sheet since he picked up the hamstring injury.
