Manchester City legend Tony Book says its crucial they find buyers for their fringe players.
Senior trio Wayne Bridge, Emmanuel Adebayor and Roque Santa Cruz are under the spotlight.
Former City skipper and manager Book told the Manchester Evening News: "If it's possible, you'd like to get them on, get some money in and get one or two you need.
"But the most difficult thing is getting them out. City pay top whack whether it's in fees or wages, and the difficult thing is recouping the fee and getting someone to pay the wages."
