Haikou - Former world number one Nick Faldo said on Sunday that Tiger Woods has work to do on his game if he is to dominate golf once again.
The American was due to lose the top spot he has held for the last five years on Sunday, with Lee Westwood favourite to take his crown despite missing the Andalucia Masters in Spain with a calf injury.
Woods's once seemingly unstoppable assault on Jack Nicklaus's record of 18 Major wins has faltered badly after a knee injury and revelations of marital infidelity that saw him take an extended break from the game.
"For a while he didn't even have a game to get him in contention on a Sunday," Faldo said.
"That will be his next goal - to have the game to get himself in contention on a Sunday afternoon. Then we'll see how strong he is again.
"I think he's got to dig deep to find his game and (we'll see) how he reacts on a Sunday."
Faldo said he hoped becoming number one would inspire Westwood - who would be the first English number one since Faldo himself - to win his first Major.
"I'd won four Majors before I got to world number one and the fifth Major probably helped," Faldo said.
"It's interesting how times have changed, where you can get to world number one without winning a Major."
Faldo said that the number one spot was important to him as a player, but big championship victories were the real prize.
"It's nice, but Majors are obviously the one because you've got to go and win them, you have to finish them off," he said.
Young German Martin Kaymer needed to finish first or second at the Andalucia Masters to leapfrog Westwood and take Woods's crown, but went into the final round nine shots off joint leaders Graeme McDowell and Northern Irishman Gareth Maybin.
Faldo, 53, said he was struggling with a stiff back and admitted his drive for playing the game had waned.
He ruled out mounting a serious tilt at another Major, saying there was no chance of him pulling off a repeat of US veteran Tom Watson's remarkable performance at the 2009 British Open, when he finished second at the age of 59.
