Luke Donald nears 'greatest achievement'

World number one Luke Donald tells BBC golf correspondent Iain Carter that an historic US and European money list double would be his "greatest achievement", as his third round 66 at the Dubai World Championship leaves him on the brink, external.

The 34-year-old Englishman will become the first man to top both money lists if he can finish in the top nine at the end of season event. Should he drop out of those positions, world number two Rory McIlroy can steal the prize with a win.

However, the 22-year-old US Open champion slipped to six off the lead following a disappointing 71. Spain's Alvaro Quiros is two strokes ahead after a 70 took him to 14 under.
