"I am very, very pleased with the performance," Martinez said.
"I think we started the game really brightly and carried a very good threat in the attacking third.
"The goal came a little bit against the run of play and from that moment on it would be all too easy to accept the momentum was Fulham's.
"But I thought we restricted Fulham really well and they only had two shots on target - the goal and right at the end, with Maynor Figueroa's special clearance.
"In between those two actions I thought we were the better side. We defended really, really well.
"It had to be something special to beat him and I was glad Franco di Santo got the reward."
