Sevilla coach Manolo Jimenez admits concerns losing Luis Fabiano to Chelsea.
In recent weeks Chelsea, despite the transfer ban placed upon them, have been mooted as serious suitors of his signature.
"I worry about the interest of Chelsea but I don't worry about what Luis Fabiano thinks," said Jimenez.
"He is a great guy and I have no doubt that he thinks only of Sevilla.
"The problem is for Chelsea and all the other teams in Europe because Luis Fabiano plays for Sevilla.
"Our desire is that he stays in Sevilla for his whole career."
