Well after a very bright 25 minutes or so the game has became very quiet as United started to sit back and allow Chelsea to have the ball.

The good news for Chelsea is that N’Golo Kanté may be able to make his return after a hamstring injury, but team news is yet to be announced. Kanté’s return could give Chelsea a much needed boost as it’s been clear the Blues have missed their dominant midfielder. Conte though will be without the injured Victor Moses once again as he hasn't recovered from his hamstring injury yet.
Man United will be without Paul Pogba yet again as he recovers from his hamstring problem, but they continue to keep pace near the top of the league and have impressed in his absence. The good news for the Mourinho though is that Marouane Fellaini and Marcos Rojo have travelled with the squad for the game and may play a part in this huge game for the club.
The Blues will welcome back other familiar faces alongside Mourinho as Juan Mata and Nemanja Matic returns to Stamford Bridge for the first time since leaving the club over the summer. The Serbian midfielder will need a big performance today if Man United are to get points out of this one.
Man United’s midweek outing in the Champions League saw them emerge as 2-0 winners, giving them a good performance as a base for Sunday’s game. With both teams chasing leaders Manchester City, a win on Sunday is absolutely crucial.
A 3-0 defeat to Roma on Tuesday gave Chelsea a bad case of the Blues, but a win on Sunday will certainly turn the spirits around in West London, especially with plenty of negativity surrounding Antonio Conte’s future with the club.
Last year’s meeting at Stamford Bridge finished 4-0 in favour of the home side, but both sides have come a long way since then and a repeat is quite unlikely. Despite that, Chelsea will like their chances at home and with motivation after an embarrassing outing in the Champions League.
José Mourinho and Antonio Conte continue to please the British tabloids as their war of indirect words continue to dominate the pre-game headlines. Both managers will undoubtedly be fully focused on coming away with a positive result.
Manchester United currently sit second in the Premier League table, aiming to gain ground on in-town rivals Manchester City. Meanwhile, the reigning champions Chelsea are off the pace in fourth, but can pull within a point of Man United with a win.
