O'Sullivan: Psychiatrist can help Suarez
Dr Steve Peters was hired by the club last November, having worked with defending world champion O'Sullivan, as well as Olympic cycling gold medallists Sir Chris Hoy and Victoria Pendleton.
Suarez, 26, has started a 10-match suspension after biting Chelsea defender Branislav Ivanovic during a 2-2 Premier League draw at Anfield on April 21.
O'Sullivan, who is on course to secure a place in this year's World Snooker Championship semi-finals, says that he can sympathise with the Uruguay international.
The 37-year-old saw Suarez's bite as "a moment of madness", which he compared to his decision to walk out of a UK Championship match against Stephen Hendry in December 2006.
O'Sullivan told the Daily Telegraph: "I understand what Suarez did, I totally get it. It's like me walking out against Stephen Hendry.
"It's a moment of madness and you think: 'Wow, what have I done?'
"Things like that can be avoided. It's about prevention."
O'Sullivan began working with Sheffield-based Peters in April 2011, and has credited him with changing his outlook on snooker and life.
He decided to take an extended break from the sport last year, only returning for the start of the World Championship in Sheffield on April 20.
But he is on course to defend his title, leading 7-1 overnight against fellow Englishman Stuart Bingham in his quarter-final, with the first player to win 13 frames going into the last four.
And the four-time world champion believes that Liverpool will become Premier League champions in the next few years if they continue to use Peters and stick with manager Brendan Rodgers.
O'Sullivan added: "If I could afford to have Steve 24/7, then I would. But if Liverpool can have him there for four or five years then they'll win the Premier League.
"I have no doubt about it. It's not a quick fix with Steve, but if Liverpool stick with him and Brendan Rodgers, they'll win the title. I have no doubt."
