World number one Tiger Woods is being tailed by golf's chasing pack
England's leading golfers Lee Westwood, Ian Poulter and Paul Casey believe that Tiger Woods's 258-week run as world number one could soon come to an end.
Woods's lead at the top of the rankings has shrunk because he took a five-month break following a sex scandal and then struggled for form on his return.
World number six Ian Poulter said: "It is closer now than it ever was, because of the points that Tiger has dropped."
The trio play in the PGA Championship, starting on Thursday at Wentworth.
"I can see anybody in the top 10 in the world getting there if they play great for a spell of three or four months and have a couple of wins and a couple of big finishes. I include myself in that bracket," added Poulter.
Based on the performances we have seen from Tiger I would agree the number one spot is up for grabs
Westwood, who is now the world number three, said: "The world rankings are about consistency and number one and number two are more achievable than they have been in recent years."
Woods missed the cut by eight in his penultimate event and then pulled out of the final round of the Players Championship with a neck strain when he was outside the top 50.
The 34-year-old's swing coach Hank Haney has quit his role and the 14-time major winner is not expected to return to golf until the US Open in June.
Casey, the defending Wentworth champion and world number eight, said: "Based on the performances we have seen from Tiger I would agree the number one spot is up for grabs.
"I was surprised about Quail Hollow and the Players' Championship. I don't know what's going on with Tiger there."

Woods is 1.2 points ahead of Masters champion Phil Mickelson in the rankings, with Westwood third a further 1.8 points behind.
"The tournaments that are coming up in the next couple of months hold huge world ranking points," continued Poulter.
"If you can win tournaments like this [Wentworth] and with the Open coming up, as well as the US Open, both with 100 ranking points - that's huge.
"If you can knock one of those over you are going to be climbing the board pretty quickly," added 34-year old Poulter.
Poulter also confirmed he would be fit to play at Wentworth after suffering from a bad neck at the start of the week.
The Englishman said: "I had to have some treatment on Monday but we should be good for the week."
There has been controversy about the changes that have been made to the iconic West Course at Wentworth, with defending champion Casey even suggesting the course should have protected status.
