The Hungary international made an immediate debut after signing on an emergency loan from Sunderland to cover for the injured Shay Given.
Fulop was playing his first game of 2010 and, although he conceded a goal early on, he recovered and helped City to a 3-1 win.
"Unfortunately I haven't been between the sticks for three months so I needed 15 minutes to get in the swing of the game," he told MTI. "But I felt good on the pitch, my team-mates helped me a lot and made my job easier."
Fulop is still delighted at the chance to move to Eastlands, adding: "Everyone is dreaming about a chance like the one I got so I said 'yes' with pleasure.
"I'm doing my best to prove that I deserved their confidence and I want to help the team to reach their aims."
Fulop, who was 27 on Monday, admits he is almost shocked by how good things are at Eastlands.
"Sunderland is a professional team but honestly I didn't think that there's a place where the conditions which surround football are better," he said.
"I could easily recognise that this team has very big goals. I was surprised in the dressing room too. There were lots of star players but the atmosphere was very family-like and friendly."
Fulop insists he is not even thinking about his own future at the moment and is focused on City's bid to qualify for the Champions League.
"I don't care about anything [regarding my future], I just concentrate on my two more games at City. I'll see later what the future brings."
