Joe Wedgwood: Lingard, Schneiderlin, Depay, Young all deserve chances ahead of the continual anonymity of Ibra and Pogba. Not. Good. Enough.
Sushant Shetty: Such luck for #mufc. Only consistent player this season and he ends up being a long term injury #bailly

Steve Howes: Why no red for Valencia, he couldn't even see the man he took out certainly wasnt going for the ball?
West Ham 1-0 Chelsea
West Ham are again denied a second as Pedro Obiang this time lashes in a volley but again, Asmir Begovic is equal to it. Terrific goalkeeping.
Ever heard of a game postponed because of an earthquake?

I think that was a genuine chance to play the ball from Antonio Valencia.
It looks a bit worse than it was.
Image source, ReutersIt's all going off in Italy and Serie A weather-wise. While Fiorentina's game with Crotone is still suspended because of the rain, Pescara v Atalanta was halted for a couple of minutes because of tremors felt from an earthquake.
That game is back under way now.

Ouch! Antonio Valencia slams into Fernando, very late and very high, that was waist high. In the book you go.

City look more threatening but Man United have done a good job on them.
They have restricted City to just one chance and now are coming into the game.

Dave in Peterborough: Who needs the bake of with everyone falling over there'll be plenty of soggy bottoms in the football. (Someone had to go there)
West Ham 1-0 Chelsea
That's a better free-kick! Dimitri Payet curls one over the wall but Asmir Begovic does brilliantly to push it away. West Ham close to a second.
Manchester United 0-0 Manchester City
Juan Mata is tripped by Nicolas Otamendi 25 yards from goal, Zlatan Ibrahimovic lines up the free-kick and goes for the Ronaldo dipper - into the wall and away for a corner. Daley Blind's set-piece is deep and Marcus Rashford loses the ball.

Chris Davies: Shocking from the ref. A clear penalty and a joke of a booking.
Lord Andrew Dennett: So far this season Pogba has just been a really expensive walking haircut!!
Andy White: Call me old fashioned but the numbers on the Man City shirts, really? Oh for the days of 1 to 11. Just where does no. 75 play?
Southampton 0-0 Sunderland
You're missing nothing from Southampton. A very drab half so far.

West Ham's performance are disguising their position in the league. I think Chelsea have played well but apart from Nathaniel Chalobah's shot, although Chelsea have dominated in the last 17 to 18 minutes, they haven't looked as if they will score.

Jose Mourinho always does his homework. Well, he can't leave his hotel room can he? He may as well.
City having more of the ball with Aleix Garcia starting well in midfield. Zlatan Ibrahimovic then wastes a good position for United with a poor, overhit ball down the left.

Man United look well organised tonight. You can see Mourinho has done his homework.

N'Golo Kante is carrying a real attacking threat for Chelsea and has a shot blocked before Manuel Lanzini prods wide at the other end! It's opening up nicely.

I've heard a lot about this stadium but we're certainly seeing a game that has passion and intensity and maybe that's because it's a derby.

CM: Forget the bake off, this is more like dancing on ice. So slippy
Speaking of wet pitches, Fiorentina's Serie A game with Crotone has been suspended midway through the first half at 0-0.
The hosts tweeted: "The rain is utterly relentless at Florence and the referee has decided to suspend play temporarily."
