Real Madrid defender Gabriel Heinze would jump at the chance to have Cristiano Ronaldo join him in Spain, but admits prising the jewel from Manchester United's crown would be impossible.
Ronaldo has emerged as Madrid's most-wanted signing in recent weeks, with sporting director Predrag Mijatovic recently claiming he wants the Portugal star to be 'the face of the new Real Madrid'.
Heinze played alongside Ronaldo during his stint at Old Trafford, and he knows better than most how difficult it would be to convince manager Sir Alex Ferguson to part with his star player.
'I would sign him, but I think it's impossible,' he told Spanish newspaper AS.
'While Cristiano is at the level he's at, and knowing Alex Ferguson, I think it is very difficult for Madrid to get him.
'He's going through a glorious spell at Manchester and Ferguson was the one who found him and who got him to the top level.
'While Ferguson's there, there's little chance of signing him.'
He added: 'I'd love to play alongside him again. And he's a kid who's always spoken highly of Madrid, but at Manchester he's coming on in leaps and bounds and it's normal that he wouldn't want to move.
'He's young and he has plenty of time to come here.'
Ronaldo missed a great chance to give his side an advantage from the penalty spot in the first leg of Manchester United's Champions League semi-final clash with Barcelona on Wednesday, which ended goalless.
Heinze admitted he was disappointed for his old side, but claimed he was not supporting them just because they were playing his new side's fiercest rivals.
He said: 'I want Manchester to win, and not because they're up against Barcelona but because I spent three great years in Manchester and I'll be grateful to them for the rest of my life.
'Against Barcelona I was just another Manchester United fan.'
One team he admits to not being a fan of, however, is his own side Madrid.
Many of Madrid's supporters are hoping their side will win the league in their home game against Barcelona in two week's time, but Heinze says he is only interested in winning and will leave rivalry to the fans.
'Winning the league against Barcelona at the Bernabeu is for the fans. I'm not a Madrid fan,' he said.
'Today I'm a Madrid professional and I'll defend their colours to the death, but I'm not a Madrid fan. I don't want to wait until the Barcelona game.'
If results go their way Madrid could win the league this weekend when they play Athletic Bilbao.
They hold a 10-point advantage at the top of La Liga going into the final five games of the season.
