Ruud van Nistelrooy has told Wayne Rooney to leave Manchester United if he is not completely committed to the club.
The England striker missed United’s last three games of the season after informing Sir Alex Ferguson that he wanted to play elsewhere.
But new manager David Moyes has hinted he wants to keep the 27-year-old, who he worked with at Everton before Rooney’s £24 million move to United in 2004.
Rooney submitted a transfer request in 2010 and his former strike partner Van Nistelrooy said it is better the Englishman goes if he cannot promise to be loyal to United.
He said: “It is a matter of how he feels. If he feels that he is committed to the club then there is an opening. If he says that there isn’t I can’t see a future for him.
“The fans would love him to stay, but it depends on the commitment. If he isn’t fully committed then it’s probably better to move on.”
Van Nistelrooy scored 150 goals in five seasons at United before being sold in 2006 after falling out with Ferguson.
He moved on to Real Madrid and played for both sides in Sunday’s charity game for the Manchester United Foundation, scoring for the English club in their 2-1 defeat.
Real’s former manager Jose Mourinho is set to return to Chelsea and Van Nistelrooy predicts an eventful second spell at Stamford Bridge for the Portuguese.
He added: “Whoever Mourinho is with something always happens. He will definitely bring some new energy to Chelsea, although winning the Europa League was obviously a fantastic success for them. It is a club with a good squad but he will do his thing as he always does.”
