Muttiah Muralitharan is on course to overtake Shane Warne as the most successful spin bowler in Test history after another match-winning performance for Sri Lanka.

Muralitharan picked up 10 wickets in the first Test against Bangladesh and now has 430 in 76 appearances, compared to Warne's 450 from 101.

The 30-year-old afterwards insisted that he was still not 100 per cent fit after dislocating his left shoulder earlier this year.

But he is focused on becoming the first spinner to reach 500 Test wickets, which would put him only 19 behind West Indies paceman Courtney Walsh's all-time Test record.

"If I keep playing for four or five years, I think I can do that," he said.

Muralitharan has already equalled Sir Richard Hadlee's record of taking five wickets in an innings 36 times.

"I'm looking for 50," he added.

Sri Lankan skipper Sanath Jayasuriya praised Muralitharan's performance, but said it was time for their seam bowlers to stop relying so heavily on the team's star performer.

"Others should also deliver. We faced the same problems in England, the fast bowlers have not been able to bowl a good line and length consistently," he said.

Muralitharan is one of eight senior players left out of the squad for the second Test, which starts on Sunday, as the selectors look to try out youngsters, but there may be pressure to keep him in the team.

Bangladesh, meanwhile, are still trying to master the art of occupying the crease for long periods.

"We play a lot of one-day cricket and that's the main reason our batsmen often fail to play the right shots in Test matches," said captain Khaled Mashud.
