So far this summer, their only permanent signing has been 34-year-old goalkeeper Benjamin Lecomte, formerly of Montpellier.
Khan wrote in today's match programme for their clash with Manchester United: “It was a summertime priority to protect the nucleus of the squad that set a Fulham record last year for most Premier League points, and we did by extending the stays of Kenny Tete and our longtime captain, Tom Cairney.
“We will continue – as we always do at this time of the year – to explore all options to strengthen our squad.
“As important this offseason was keeping and rewarding the next generation of Fulham Academy talent that we feel will make a positive impact on our First Team today and in the years to come.
“That’s why we focused on and ultimately delivered long-term deals for three of our most promising youngsters who have progressed or are advancing through our Academy in Josh King, Luc De Fougerolles and Seth Ridgeon.
“As we saw Saturday at Brighton, Josh is already making a statement. In fact, his performance earned him Man of the Match honours from our supporters at fulhamfc.com, and deservedly so.”
