Andy Murray expects a tough test against home favourite Milos Raonic after cruising into the last 16 of the ATP Rogers Cup in Toronto last night.

Buoyed by his gold medal triumph at the Olympics, the world number four dominated from start to finish against Italy's Flavio Cipolla - ranked 93 places lower in the world rankings - and swiftly wrapped up a 6-1 6-3 win.

The 25-year-old will meet Canadian number one Milos Raonic tonight for a place in the quarter-finals, and acknowledges the 16th seed will provide tricky opposition.

"It will be tough. He'll obviously be very motivated playing in his own country," Murray said of the 21-year-old on http://www.atpworldtour.com.

"He's improved a lot over the last year, year and a half. He's playing really, really good tennis. Very big guy with a big game. Serves well and hits the ball very hard."

Murray, bidding to win his third Masters 1000 title in Toronto and his ninth overall, needed just one hour and 21 minutes to beat Cipolla with the first set lasting half an hour thanks to two breaks of serve.

The Roman beat Estonian Jurgen Zopp in the first round, but looked second best throughout against Murray, who was given a first-round bye.

Murray fired three aces and seven winners as Cipolla struggled to keep pace with the Scot, who found great success coming forward as well as from the back of the court.

The trainer was required with Murray having knee trouble and Cipolla briefly took advantage by forcing the British number one to charge around the court.

Murray was unable to maintain his first-set intensity and Cipolla fared better in the second before the Scot's break in the fifth game proved decisive.

"After playing for eight weeks on grass pretty much, it's very different here," the second seed said. "The ball is very quick compared with Wimbledon. It also bounces much higher.

"The court is much slower as well, so there are a lot of things to change. I only got a couple of hits on the court, so it was good to play a match and get a win fairly comfortably."
