O'Sullivan has the talent to do it, but his motivation is always a question. I can't really see him winning four more World Championships.
Still, this time around he is playing great again, and leads 9-7 before the final session of the quarter-final match against Neil Robertson. The only remaining player in the tournament I can see beating either of them, is Maguire. A final between O'Sullivan and Maguire could be great. I was hoping for Hendry - O'Sullivan, but Maguire played some outstanding snooker in the quarter-final.
I'm happy Hendry got a maximum in his last World Championship - it means he goes out in style despite the bad result in the QF.
