Rooney admits Man Utd players already eyeing first derby
Having gained the benefit of Chelsea's draw with Manchester City at Stamford Bridge on Sunday, United are now looking to maximise their advantage, knowing the first derby of the season is looming at the Etihad Stadium on December 9.
"We know City and Chelsea will be looking out for our results as we look out for theirs," said Rooney.
"But it is important for us to concentrate on our own performances and make sure we get the wins because there are a lot of games coming up.
"It is tough period and I am sure the manager will use his squad. We just have to make sure we come through for him."
