MARK Williams, snooker's world number one, may have the talent to be at the top of his profession but he still needs to learn a lot in the game, says the sport's leading coach, Frank Callan.

Callan, who is willing to help the Welsh star, said: "Mark will have to find out in his own time that natural talent is one thing - but learning about the game is something else."

And Callan, former coach to Doug Mountjoy, added: "He has still got lots to learn. There is no doubt in my mind that Mark has a lot of things going for him - and that includes a lot of bottle."

Williams crashed out of this year's World Championship at the Crucible in Sheffield against up and coming Irish star Joe Swailes, but Callan believes the Welsh Dragon will bounce back.

"If I know Mark he'll be on the golf course right now, away from snooker. But he is shrewd enough to remain at the top."

However Callan, who recently split from coaching seven times world champion Stephen Hendry, who also crashed out of this year's World Championship, says Williams is still learning.

"Mark is still in the process of learning - he now knows how easy it is to come unstuck. But he is still the number one - something he has in his favour," said 79-year-old Callan.

And Callan spoke about Williams' fellow Welsh snooker ace Matthew Stevens.

"Matthew is doing very well. He is in the game for his dad. I've spoken to him and commiserated with him, following the loss of his dad," said Callan.

He added: "Matthew's dad went with him to every tournament - and he's missing him. But Matthew will be up there, with all the probables, in the years ahead.

"Mathew is level headed and I'm sure he will keep his feet on the ground".
