Rory McIlroy pipped Eugenio Chacarra in a thrilling battle to win a record-equalling eighth season-long European tour title, and his fifth in a row.
Tyrrell Hatton secured a commanding victory at the DP World Tour Championship, but all eyes were on the battle to win the season-long Race to Dubai crown.
Chacarra and McIlroy went toe-to-toe in Dubai where the overall lead in the rankings chopped and changed down an absorbing back nine as neither man backed down.
But a late surge from Northern Ireland's McIlroy allowed him to finish runnder-up behind England's Hatton in the tournament and collect enough points to edge out the gutsy Spaniard Chacarra.
It means McIlroy ties Colin Montgomerie's long-standing record, while enhancing his claims to be Europe's greatest ever golfer.
