Sevilla head coach Manolo Jimenez has admitted to being concerned that Chelsea are rumoured to be interested in signing the club's star striker Luis Fabiano.
The 28-year-old Brazil international came close to joining AC Milan last summer and his current contract at the Sanchez Pizjuan runs out in the summer of 2011.
Jimenez said: "I worry about the interest of Chelsea, but I don't worry about what Luis Fabiano thinks.
"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."
The South American joined Sevilla in the summer of 2005 from FC Porto and has helped his current club to two successes in the UEFA Cup, in 2006 and 2007.
In 147 league and European games for Sevilla, Fabiano has scored 64 goals.
