The 30-year old Senegalese striker, currently on loan at Championship club Leicester City, has made just 15 first team starts for the Cottagers ion the past three seasons and knows his time there is coming to an end.
"It has been a little bit frustrating for me at Fulham," Kamara told the Leicester Mercury.
"At the start of the season I was doing well and I was the second-best scorer in the team with five goals in 11 games, but I am at the end of my contract and they made the decision not to play me. This is football.
"I enjoyed my time at Fulham but now it is over and I say good luck to them."
The former West Bromwich Albion forward also said he could remain with the Foxes if all goes well.
"There is definitely a possibility of me staying if it all goes well," he added.
"I see this as a fresh beginning. I like to push myself and this is a big challenge."
