Benni McCarthy has warned team-mate Roque Santa Cruz that he risks harming his career should he decide to quit Blackburn Rovers in the January transfer window.
The Paraguay striker has been strongly linked with a move to Manchester City, where he would rejoin former Rovers boss Mark Hughes.
However, McCarthy has urged his strike partner to stay at Ewood Park where his career has been revitalised since his arrival from Bayern Munich 18 months ago.
"My message to Roque is that the grass is really not that green on the other side," he said.
"Here you are appreciated and loved, but go elsewhere and you have to start all over again.
"That makes it really, really hard to get going and who knows whether you will be as popular as you were at your previous club when you join your next one?
"Blackburn is a fantastic place to be. It is a great family club and, when you play here and you are a family-orientated person, it is amazing.
"It is very close-knit, the people are nice and they always try to do everything they can for you and your family to make you feel at home.
"That is the most important thing you can have in football because, if your family life is good, then the football side will get the best out of you."
