Ronnie O'Sullivan has taken a clear jibe at his snooker rivals following victory in his 15th Masters semi-final.
The Rocket claimed younger players have 'slow' brains following his win over Shaun Murphy.
O'Sullivan was below par in his first two matches of the tournament against Ding Junhui and Barry Hawkins.
But the world No 1 was back to his mesmeric best at Alexandra Palace on Saturday as he seeks a record-extending eighth title.

He led 3-1 at the mid-session break before Murphy reduced the deficit to one frame.
Murphy played well with two 100-plus finishes but O'Sullivan was levels above and stormed through with a 6-2 win.
He will now play either Mark Allen or Ali Carter in Sunday's final at Ally Pally.
O'Sullivan will become both the youngest and oldest winner of the tournament if he is victorious.
He insists he still feels youthful, even if his age says something different.
O'Sullivan then taunted his fellow players, claiming they still can't beat him even when he's been suffering from several physical issues.
He said: "I don't feel that old. I know my age is but I feel young in my mind, I feel young when I'm round the table.
"I feel a lot younger around the table than I do when I'm playing these young players, but they look old!
"Their brains are quite slow. I still feel like my brain is still pretty quick around the snooker table, which is enough.
"They need to get their acts together because I'm going blind, I've got a dodgy arm and bad knees!
"They still can't beat me!"
O'Sullivan put on a show for the crowd at the London venue.
Former player Steve Davis questioned O'Sullivan this week, claiming he should focus on the result more than his performance.
O'Sullivan has responded, insisting his intention is not to entertain but says it is an added bonus if he does.

He added: "I just heard what Steve Davis said. He said I shouldn't try to entertain the crowd.
"But I never have tried to entertain the crowd, I've just always tried to go out there and play snooker the way I know I can.
"If the crowd enjoy that, then great, but that's never been my sort of philosophy.
"I just want to play the game well and if I don't play well then I get quite frustrated.

"At the start of the match there were a few mistakes but then I cleaned it up a little bit.
"I need to do that these days because I can't pot as well as these guys but I can make good breaks amongst the balls and make up for it that way. I won the match."
