McCormack's exploits in front of goal last season resulted in plenty of interest in his signature, but after he opted to make an £11m move to West London, the Scottish international has revealed that he is keen to play his part in a successful year for the club.
The 27-year-old told the club's official website: "Having spoken to the manager, very quickly, I realised that this was the club for me. The transfer took a little longer than I initially anticipated, but I'm just happy to be here now.
"I've been with the boys for a few days, and I have to say that I'm really impressed by what I have seen. I just want to add to the squad and play my part in what I hope will be a successful season ahead.
"From that first discussion, I felt wanted. I could tell that they rated me as a player, and that's a big thing. It made a real difference. There was speculation in regards to other teams, but Fulham was where I wanted to be."
McCormack scored 28 goals for Leeds United in the Championship during the previous campaign.
