Fulham are in talks with Sporting Lisbon over a possible deal to sign youngster Wallyson Mallman on loan.
The 22-year-old central midfielder spent last season on loan at French club Nice and has been told his first-team chances will be limited at Sporting.
The Brazilian is one of a number of players suggested to the Whites during talks over compensation for Bryan Ruiz, who Fulham sold to Sporting last summer.
Sporting have not yet paid the full £1m fee and have offered to give Fulham a player on loan in an attempt to reach a settlement.
The Portuguese outfit are also prepared to part with Ewerton, Paulo Oliveira, Jefferson, Carlos Mane, Esgaio, Alberto Aquilani, Juri Medeiros or Matheus Pereira.
