It's a big day in Manchester this weekend as Jose Mourinho and Pep Guardiola resume their rivalry at Old Trafford.

United and City have enjoyed 100 percent starts but someone's run will come to an end this Saturday.

The Old Trafford clash sees Jose Mourinho and Pep Guardiola resume rivalries after a series of ill-fated encounters in Spain.

It promises to be a blockbuster but as ever, there is plenty more at stake across the Premier League.

Pep Guardiola will do without Sergio Aguero for the Old Trafford showdown.

The Argentine has been handed a three-game ban for an apparent elbow on Winston Reid during the win over West Ham before the international break.

Ilkay Gundogan and Leroy Sane are also fit and could be on the bench but the clash should come too soon for Vincent Kompany.

Jose Mourinho meanwhile has problems at the back with Antonio Valencia also returning late from international duty.

Luke Shaw pulled out of the England squad but is expected to be fit, while Henrikh Mkhitaryan is a doubt.

Following his winner at Hull and a hat-trick for England's Under-21s, Marcus Rashford is pushing for a start. He could come in for the out-of-form Anthony Martial.
