Murray despite victory is looking for improvement when he takes on World No.7, Alexander Zverev for a place in the third round and he believes that the German will be a 'good test' for him next up.

"I thought I moved well today. That was probably the thing I was most happy with and probably the thing I was most apprehensive about going into the match," said Murray. "I thought I moved pretty well. My tennis could have been better. I did some things well at the end, but I could definitely improve in terms of my game."

"[Zverev has] obviously been up at the top of the game for a number of years now,” said Murray. “It will be a good test for me, for sure… He moves well for a big guy, solid off the ground. [He] has struggled at times with his serve. When he's serving well, he's obviously one of the top players in the world.”
