The Russia international has been in talks with the Cottagers in recent weeks over turning his temporary contract into a permanent one. However, the 28-year-old has claimed that he will look elsewhere if an agreement isn't met.
"After three or four months, I feel that I have found my place in England and I want to play in this league," Pogrebnyak told Sport-Express. "I feel great desire and strength inside me and my age will not work against me.
"We couldn't agree anything with Fulham so far, but I hope everything will be alright. If I don't play for Fulham, I hope to find another team.
"It would be good to sort this out before the European Championship, because there is a risk there. Anything could happen, and if you get injured then no-one will want to sign you."
Pogrebnyak scored five goals in his first three games for Fulham after joining in January.
