Muttiah Muralitharan is 5/2 to notch his 800th Test wicket in his final match in Sri Lanka, according to Ladbrokes.
The legendary spinner takes his final bow in Galle and needs eight more wickets against India to reach the phenomenal milestone.
Ladbrokes make it 100/1 that his Test haul of wickets is beaten by any international player in the next 25 year.
Spokesman David Williams said: "Murali's record almost defies belief. Whether or not he makes it to 800 we doubt anybody will come close to him for many decades."
