Fulham manager Slavisa Jokanovic is allegedly frustrated with the club's lack of activity in the transfer market during the final weeks of the summer window.
The Whites boss is desperate to further strengthen his squad to mount a promotion challenge in the Championship this term, according to Sky Sports News.
The report goes on to say that the Serbian is targeting additional attacking options, with Blackburn Rovers winger Ben Marshall said to be top of his wish list.
Jokanovic has already brought in nine new faces this season, with Sone Aluko, Floyd Ayite, Kevin McDonald, Shaun Maloney, David Button, Michael Madl, Jozabed Sanchez, Denis Odoi and Tomas Kalas arriving at Craven Cottage over the summer.
Fulham have made a solid start to the new season, with two wins and a draw so far.
