Wayne Rooney is not for sale

Striker Wayne Rooney is not for sale at any price, Manchester United chief executive David Gill, according BBC Sport.

Rooney is in brilliant form with 21 goals this season which could trigger an offer from Europe, with Barcelona and Real Madrid said to be interested.

But Gill said: "Unless Alex agreed to it, we would not accept an offer, regardless of the value, for a player we want to keep."

Gill said they had a 35m Euro bid for France striker Karim Benzema refused.

United manager Sir Alex Ferguson had been tracking the talented 22-year-old for months but saw his offer rejected by Lyon, who accepted a 41m Euro bid by Spanish giants Real Madrid in July 2009.

"We didn't get Benzema but we did offer 35m Euros," said Gill.

"It was just one phone call to the States saying we would like to make an offer for him 35m Euros and they said 'fine'. We did it, but he went to Real for something like over 40m Euros.

"But Alex has gone on record saying that was too much."

Gill also alleviated fears that United's owners, the Glazer family, would sell Old Trafford or the club's Carrington training ground.

"Wayne has a contract through until 2012," said Gill. "He has gone on record to say he wants to stay and we want him to stay.

"I'm sure that will be addressed in the close season. We hope that would be the case as we want to put him on a new, long-term contract. He's 24 and got the best years of his life ahead of him.

"Very few players, particularly UK-based players, want to leave Manchester United."

This is my club and I'm very happy here," said Rooney.

"My family live 30 minutes away. I'm perfectly happy and there is no reason to play my football anywhere else. Manchester United are the biggest club in the world."

"I'm sure if he needed that money, it would be spent," said Gill, who oversaw the arrival of defender Chris Smalling from Fulham for about £7m

Concerned by the £716m debt burdened by the Glazers, a number of fans plan to enter the ground 10 minutes after kick-off to expose empty seats at the ground with millions of people watching around the world.

But Gill believes any protest would be counterproductive on a night when United need their supporters most.

"I would appeal to the fans to be sensible and get behind the team," he added.
