"My aim is to take 700 Test wickets and I know I can reach there," said Muralitharan, who has already grabbed 549 wickets in 93 Test matches.

Only Australian leg-spinner Shane Warne is currently ahead of Muralitharan, with 589 Test wickets.

"You need just a couple of good seasons and around 35 Test matches to reach the 700-mark," Muralitharan said, adding the secret of his success was to "try hard" and "enjoy playing the game".

The Sri Lankan off-spinner, 33, said he did not believe he was the only bowler capable of reaching the landmark.

"No, I am not chasing Warne's world record. Nor do I know when I will edge past him, said Muralitharan.

"There are three bowlers -- Warne, Glenn McGrath and Anil Kumble -- who are also capable of taking 700 Test wickets. They are also in the fray."

Australian fast bowler McGrath has already captured 508 Test wickets and Indian leg-spinner Anil Kumble 461.

Muralitharan said that fitness problems alone could upset his plans.

"It all depends on how long I play. I missed international cricket last year because of injuries," he said.

Muralitharan returned to Test cricket last month after a shoulder injury, only to prove he had not lost his magic.

He grabbed 17 wickets in two Test matches to play a significant role in his team's 2-0 series victory over the West Indies.

Asked whether he got bored taking seven-eight wickets in every Test, he said: "No, I never had such a feeling.

"I don't get seven-eight wickets in every match. Perhaps six-seven. My job is to take wickets. That's why I am playing for Sri Lanka. I am not playing to break records, but to contribute to my team's victories," he said.

"Winning is more important. Cricket is a team game and my aim is to try to get as many wickets as possible for my team."

Muralitharan, called a few times for throwing in his controversial career, has a record combined tally of wickets in Tests (549) and one-dayers (372).

He surpassed Pakistani paceman Wasim Akram's total of 916 wickets (414 in Tests and 502 in one-dayers) only in the second and final Test against the West Indies at his home ground in Kandy last month.

"I was not aware of this record," said Muralitharan.

"It is nice to know I am the highest wicket-taker and I will try to achieve more."

The Sri Lankan said he had no plans to quit one-day cricket and concentrate only on Test matches.

"I want to play in both forms of the game as long as I can. I enjoy playing in one-dayers and Tests. I can reconsider my decision only if I am troubled with form or fitness problems."
