Manchester United boss Louis Van Gaal has grown weary of questions on struggling Wayne Rooney
Louis van Gaal said he was "sick" of answering questions about Wayne Rooney's form following a dull and goalless Manchester derby.
United and City played out a scoreless stalemate for just the third time in Premier League history yesterday.
Jesse Lingard rattled the bar and Chris Smalling drew a late save from Joe Hart, but otherwise the hosts rarely looked like getting the breakthrough against a defensive-minded City side.
Just like he did against CSKA Moscow on Wednesday, Rooney struggled. The United captain, who turned 30 on Saturday, failed to test Hart as Anthony Martial, deployed again on the left, looked by far the most dangerous player in red.
Van Gaal bristled at the first mention of Rooney's name in his post-match press conference.
"I have to talk about Rooney every week, why?" the United manager said. "You have your opinion - write it. I don't give any more answers about Wayne Rooney. I am sick of them."
In fairness to Rooney, he was not the only one who struggled to make an impact on what was a poor game devoid of risk-taking.
Without Sergio Aguero or David Silva, City looked toothless in attack in the 170th Manchester derby.
City manager Manuel Pellegrini admitted he altered his tactics in order to play more defensively and get the point that was required to send his team back to the top of the league.
He said: "We are back at the top of the table. It was a very tactical game. I prefer to play in another way but we defended well.
"Unfortunately for the fans it was not a very attractive game. If you can't win, then don't lose it. People have said that we can't defend and in the second half we did very well.
"We lost so much possession of the ball and we had to concentrate. United had two late chances but overall it was close.
"I am satisfied with a point but I don't like to play this way."
Vincent Kompany, meanwhile, dismissed speculation that he has fallen out with Pellegrini.
Kompany started on the bench in the two games prior to the Manchester derby after he went against Pellegrini's wishes and played for Belgium against Israel.
Pellegrini did not want his captain to play for his national side because he was carrying a calf injury.
The City boss recalled the centre-half against United and after the 0-0 draw, the captain played down reports of a rift between him and his manager.
"Everyone knows how much this game means to me," Kompany said.
"I was disappointed to be left out of the team but it is all about opinions.
"There is no problem with me and the manager."
