The 29-year-old has been in impressive form since his deadline day move from Manchester City to west London.
"I am loving it to be honest," he said. "I go home happy and I look forward to training now on Tuesday and the game again.
"You just know how to prepare yourself.
"It’s not so much frustrating, it’s just that if you don't know when you are going to play, how do you focus on a game?
"That's part of football, though, and if you are going to be at a big club you have to deal with it.
"I had it at Chelsea and Man City and you know it's not about yourself, it's a team game.
"If you are hurting inside, you can't really show it because you want the team to do well because that's part of football.
"I was hurting inside because I am a footballer and I want to play but that's just the way it goes sometimes."
"We have played three games and I thought we gelled quite well for a team that has just come together," the player added.
"But obviously there is still a lot to be done and still stuff we are going to work on at the training ground."
