I'm not big beast yet, insists Murray

Andy Murray insists that despite winning successive Masters titles, he is still far behind the big three elite of men's tennis.

"I've beaten Federer, Nadal and Djokovic, but I'm still a long way behind the top three," Murray said after muscling to the Madrid Masters title with a 6-4, 7-6 (8-6) title victory over France's Gilles Simon.

"I've played great the past three months," added the losing US Open finalist to Federer, whom he defeated in the Madrid semis.

"But those guys have been unbelievable the past couple of years. They are so consistent on every surface.

"They've been awesome and I'm not close. I've got a lot of work to do."

Murray, who has now won four titles this year including the Cincinnati Masters, said that his weekend win over Federer extracted a big emotional toll.

"After playing Saturday it was tough for me, I was mentally tired," the world number four said.

"My legs felt a bit heavier today, due in part to the situation I was in. The lactic acid builds up.

"I didn't come here expecting to win the tournament. I'd practised very well but there is a difference between that and playing well. But now I'm building some more confidence."
