Manchester United chief executive David Gill insists the club would never sell Cristiano Ronaldo, amid reports Real Madrid are lining up a £50m offer.
"There's no chance of us selling him, no way, whatever the bid," he said.
"Cristiano signed a new contract last season to 2012 and we are not a selling club. (Manager) Alex Ferguson has never let a player go he didn't want to.
"He is happy here. Alex knows Ronaldo's mind and what he's about - everything about him is Manchester United."
Ronaldo is featured on BBC's Football Focus on Saturday, and the Portugal international says the team need to win trophies to prove their worth.
606: DEBATE
Ferguson says the current squad, who are in the hunt for the league, Champions League and FA Cup titles, is the best he has had but Ronaldo told Football Focus: "Individually, the talent is great.
"But if we don't win anything, people will say this is not the best group of players. Trophies are the most important thing."
United signed Carlos Tevez, Nani, Anderson and Owen Hargreaves last summer to bulk up their squad after winning the Premier League last season.
But they were beaten in the FA Cup final by Chelsea and were knocked out of the Champions League at the semi-final stage by AC Milan.
Ferguson has already lauded the quality at his disposal and Ronaldo has echoed his manager's sentiments.
"I would say in my time, maybe this is the most talented United team," he added.
"For me, he is an exceptional player"
Meanwhile, Ronaldo has won praise from Arsenal rival Cesc Fabregas.
"He (Ronaldo) is amazing," said Fabregas, whose table-topping Arsenal side are two points ahead of United.
"I admire his physical body, his power, he is so quick with the ball and he has such strength.
"He is a player that at any moment can score a goal for the team and make the team win - even if it is a header, left or right foot.
"For me, he is an exceptional player."
He added: "It is good that people say they enjoy watching Arsenal, but when I watch teams like Manchester United, I really enjoy watching it myself."
