The 23-year-old was in London on Tuesday to undergo a physical examination and Fulham are happy that he can handle the rigours of Premier League life and have offered him a two-year contract.
Gecov is delighted to have secured a switch to Craven Cottage and admits he cannot wait to get started.
He told isport.blesk.cz: "I am enormously happy because it has always been my dream to play in the Premier League."
Gecov's agent claims his client should have no problem adjusting to life in England, with Fulham having put him through a thorough medical.
Jiri Muller said: "It was very demanding. I have never seen such a thorough medical as this. About 20 doctors and other experts checked Marcel.
"He underwent physical, functional, medical and psychological tests and everything turned out okay in the end."
It is understood that Fulham, who saw off interest from Sparta Prague to land Gecov, have paid Slovan Liberc around £700,000 for the former Czech Republic international.
