Premier League new boys Fulham will try to re-sign the players that spent last season with them on loan from other clubs.
On-loan players who had successful stints with the Cottagers last season include the Chelsea duo of Tomas Kalas and Lucas Piazon, Brighton's Oliver Norwood, Newcastle striker Aleksandar Mitrovic and Southampton defender Matt Targett.
The Cottagers have an option to buy Kalas permanently from Chelsea for a fee of £8.5 million, though they will try to negotiate for a cheaper price.
After arriving on loan at Craven Cottage from Newcastle during the January transfer window, Mitrovic scored 12 goals to help the club seal promotion to the top-flight.
Targett went on to establish himself as a first team regular, making 21 appearances after also joining during the January transfer window.
