Bolton Wanderers boss Sammy Lee admits he fears losing star pair El Hadji Diouf and Nicolas Anelka.
Anelka has played for seven clubs during a nomadic career - while Diouf left Liverpool under a cloud three years ago.
Lee hinted at the striking duo's track record when he said: "I certainly don't want them to go - and as has been mentioned before, certain people have had 'previous' at being at football clubs about wanting to leave.
"It's not just Bolton Wanderers - there is a trend - but obviously we'd like to keep our best players."
