Cristiano Ronaldo believes Manchester United's 1-1 draw at Celtic is perfect preparation for their looming clash with Arsenal.

"We had enough chances to win but a draw is good," he told MUTV. "We now have eight points and it looks like we're through to the next round.

"Sometimes the goal doesn't come but in the second half we played fantastically and created a lot of chances. We played in their half of the pitch and played a lot better in the second half.

"We could have scored more than one. The goalkeeper made a few good saves, but sometimes it's not possible to score goals. Last week we scored four goals, tonight we scored one goal. Celtic didn't cause us any problems in the second half, so I think we deserved the point."

Ronaldo and co. now gear up for a trip to the Emirates Stadium to face Arsenal on Saturday lunchtime. He added: "The aim is not to lose a game. We came [to Celtic] to win three points. It wasn't possible tonight but we did get one point and now we're thinking about the next game. I think the team is playing well."
