Melbourne: Australian spin wizard Shane Warne feels that his greatest rival Muttiah Muralitharan's world record of almost 800 Test wickets will never be beaten.

"I don't think it will ever be broken. Even though so much more Test cricket is played these days, I think Murali's record will stand for a long, long time and probably forever," Warne was quoted as saying by the Herald Sun.

"You just have to work it out by numbersu00a0-- for that record to be broken someone has to play 140-150 Tests and take 5-6 wickets a Test. That will take some doing."
