Djordje Petrovic says playing for Chelsea is a dream come true.

Stepping in for injured No1 Robert Sanchez, Petrovic has helped Chelsea win four of their last five matches in all competitions.

“It's like a completely different sport [in the Premier League]," the former New England Revs keeper said. “It is a lot faster and you don't have time to think when you have the ball at your feet.

“It is different, but I enjoy it here because that is a dream for us… everyone wants to play here and you can improve by playing here.

"We have pressure, but my team-mates help me a lot, and I try to help them. Everyone helps. The coaching staff are also helping me and everyone.

"The goalkeepers and goalkeeping coaches are all helping and we have a good chemistry between us. If I have something to ask Betts [Marcus Bettinelli], Robert [Sanchez] or Lucas [Bergstrom], we all help each other, and I am also helping.

"Before my first game, before Sheffield United, they said 'no pressure'… and I felt that pressure, to be honest, and they were just telling me to play my game, and that's it.

"I just look at the next game and I just want to help the team.

"The decision is not on me, it is on the coach and that's it. We push each other and have a good chemistry and that's all that's important."
