Murray believes he is already a better player than he was last year [AFP]

Nikolay Davydenko and Andy Murray will meet in the semi-finals of the Qatar ATP Open, after both eased through their quarter-final ties.

The wins on Thursday set up a repeat of their 2007 semi-final in Doha, which Murray, the world's number 11 and this year's third seed, won.

Murray showed versatility and intelligence in overcoming Swede Thomas Johansson 7-6, 6-0.

"In the second set I was a lot more confident. I had the momentum and his head went down after the first set."

"I was expecting it to be a really tough match and it went like that in the first set and then I upped my game a bit."

Murray said that his knowledge of his opponents, including Johansson, 32, has assisted him in his tennis.

"I have watched a lot of tennis, when I was 15 or 16. I watched a lot of these guys playing and know a lot about most players."

However, Murray did not say that he would be the favourite in his semi-final match, despite believing that he is a better player than he was last year.

Ljubicic goes through

Powerful base-line play dominated Davydenko's match against fellow Russian Dmitry Tursunov, with the 26-year-old pulling out some outstanding passing shots.

The Russian, ranked number four in the world and the tournament's top seed, won in two sets, 7-5, 6-3, setting up what promises to be an absorbing meeting with Murray on Friday.

In the other quarter-finals Ivan Ljubicic, the defending champion, won 6-3, 6-7, 6-3 against the belligerent German Philpp Kohlschreiber, and Stanislas Warwrinka of Switzerland, beat Agustin Calleri 6-3, 6-0.

He now faces Warwrinka, the world number 36 who he has beaten in all of their previous three matches.
