Manchester United assistant manager Carlos Queiroz has urged Cristiano Ronaldo to spurn the advances of Real Madrid and remain at Old Trafford.
Ronaldo, 23, has been linked with a world-record transfer to the Spanish giants this summer after refusing to pledge his future to the European and Premier League champions.
United insist last season's 42 goal top-scorer is not for sale and Queiroz believes his Portuguese counterpart should stay with the Red Devils.
"Manchester United is very special," said Queiroz, who himself coached Real Madrid before being axed after just one season.
"Because of that we know how to surround Cristiano completely with all the affection and all the attention he deserves.
"However, not speaking is the most sensible course of action at this moment, so that we don't contribute to a less than positive spectacle and so we don't aid those whose interests are difficult to identify."
Meanwhile, Queiroz has denied reports that he could leave Sir Alex Ferguson's backroom staff to take the Portugal job.
Luiz Felipe Scolari's decision to take over at Chelsea has left the Portuguese FA seeking a new coach.
"I'm not going to put myself in the market," he continued.
"The decision on the national coach should not be a result of those who make themselves candidates, but a decision that is conscious, rational and based on what the federation judges is necessary for the team.
"I'm not going to tell you whether or not I'm contacted. That way I know for sure that it will be dealt with in due form and in due place."
