Fulham boss Martin Jol described the summer market as his "worst ever".
The Dutchman is realistic about Fulham’s chances this season after seeing top players exit Craven Cottage in the summer.
Among the high-profile departures were Mousa Dembele, Dickson Etuhu, Danny Murphy and Clint Dempsey.
He added: “This transfer window was probably the worst ever because I really thought I would keep my best players besides Clint Dempsey.
“I knew Dimitar Berbatov was on the fringes and thought if I can add him maybe we can go for the top six.
“Then in a couple of days it all changed. I was quite frustrated.
“Everybody tells me that we need to be in the top 10 even when Dembele and Dempsey have gone.
“The only thing I can do is keep my mouth shut and work hard.”
