Ronnie O'Sullivan has never won the Pokerstars.com Masters and World Championship in the same year. The sponsors of the latter, Betfred.com, are offering 16/1 on him doing so in 2010.
Ronnie seems to play well in spells. Last year he played some great stuff to win a fourth Masters crown. At the Crucible he failed to reproduce this form.
So the good news for his many fans is that if he fails to land a fifth Wembley title this week, he could be a racing certainty to become world champion for a fourth time in May. Only once in the last six years has he failed to win either title.
He faces a very tough opening round encounter in the shape of Australian Neil Robertson, who lies a place behind him at third in the current provisional rankings.
One concern I would have for O'Sullivan is his constant chopping and changing of cues. Even for a talent such as he is, this doesn't seem like the most sensible policy.
Yes, he won the Masters last year with a brand new model - a remarkable feat - but it should also be remembered that Joe Perry had the pink to beat him 6-4 in the first round.
O'Sullivan's record in the Masters is second only to Stephen Hendry's and if he wins the title on Sunday he will have won in excess of £1m in prize money at Wembley.
It's 15 years since he first scooped the trophy and he remains the favourite to do so again this season.
Robertson beat O'Sullivan in the quarter-finals of the first two ranking events he won and is a confident, attacking player in much the same style as his opponent.
He played very well at Wembley last year but lost 6-3 to Stephen Maguire in the quarter-finals, a match which ended with five successive centuries.
Neil went home for Christmas and said it was extremely hot, not a problem he has encountered since returning to the UK.
But will he manage to freeze O'Sullivan out?
