"Sometimes he waits too much and simply tries to move the other guy," he added. "So I have to attack and put pressure on him, that's my only chance to win. He's good from the baseline and good at the net."
Murray cruised past Edouard Roger-Vasselin 6-1, 6-4, 6-4 to extend his remarkable record against French players to 37 wins from 38 matches.
The Scot accepted, however, that he will have to raise his performance levels against the experienced Llodra.
"He's been a great doubles player and very good at singles for a long time," he said.
"He's got a lot of experience and makes it difficult because of the way he plays.
"You don't see guys playing like that much nowadays and when you do play against them it normally takes a little while to adjust.
"It's going to be tough but I have always enjoyed playing guys that come forward in the past. Hopefully I can play a good match against him."
Murray was never seriously troubled by Roger-Vasselin although the world number 101's improvement as the match progressed prevented the Scot from experimenting too much.
"Once you get ahead you can try a few things when you're returning serve if you want to," he said.
"Once I got a break up in the second I would have liked to have tried a few different things but he started to play more aggressively and so I had to just play solid throughout.
"I guess the match court is not the best place for an experiment, (You) do that on the practice court."
