It was the second time that Diouf has been punished for a spitting offence during his time in England, following the episode in Liverpool’s UEFA Cup game against Celtic when he turned his anger on a fan of the Scottish club.

Taylor is concerned that Diouf’s temper could boil over again and result in him committing another similar act.

Taylor predicted that the FA would be quick to act, and advised Diouf to look for psychological help.

“It’s certainly not acceptable,” Taylor told BBC Radio 5 Live.

“People should be aware we do have a disciplinary system within football, both at club level and Football Association level. He’s apologised, he’s also been fined, and it’s likely he’ll also be charged by the Football Association I’d imagine.”

Diouf is at Bolton on a season-long loan from Liverpool. While at Anfield, his misbehaviour against Celtic in March 2003 was punished by a £5,000 (€7,000) fine from Glasgow Sheriff Court and a two-game ban from UEFA.

“It’s strange that he’s not learned that lesson,” said Taylor. “I’m pleased the way the club are going to have words and try to have professional counselling to understand why he does that when he’s upset.”

Asked by Breakfast Show presenter Nicky Campbell whether Diouf needed “a kick up the backside”, Taylor responded: “Bearing in mind he’s a high-profile professional player, it’s happened more than once, from that point of view I would say yes.

“It’s a particular problem that can’t be accepted by his club or his fellow professionals.”

According to Taylor, ensuring that Diouf does not re-offend is “half the problem”.

And Diouf could face a more stringent punishment should he err again, with Taylor revealing that repeating the same offence can result in a player ultimately being fined up to six weeks’ wages.
