After being banned for 9 international games and from all football for 4 months we look at the previous controversies involving Luis Suarez
Suarez needs to be frustrated on the training ground so he can learn how to respond differently, a sports psychologist has told ITV News.
Liverpool manager Brendan Rodgers believes striker Luis Suarez's transformation is a true credit to the player.
Luis Suarez has pledged that he will not bite again after finally being formally unveiled by new club Barcelona.
The Uruguayan has been banned from football for four months after he bit Italian defender Giorgio Chiellini during the World Cup.
"I say to all the fans: don't worry because I won't do that anymore," the Associated Press quoted the striker as saying.
Asked during a press conference at the Nou Camp what he was doing to ensure no repeats of the incident, Suarez said: "I am speaking to professionals - the right professionals," he added
Asked whether he should have apologised earlier for the bit on Chiellini, he added: "I don't like having to go back.
"That's something that happened and afterwards I was really depressed and didn't feel like doing anything.
"But then I spoke to my psychologist and he said I had to face it and say sorry.
"I did that and now I would rather focus on the present which is Barcelona."
'On an emotional day for me would just like to say what a pleasure it has been playing with an amazing talent such as Luis. I would like to thank him for his outstanding contribution on the pitch and to wish him and his family all the best on his new adventure in Spain'
FIFA has re-iterated that Luis Suarez will not be allowed to train during his four-month ban for biting despite reports to the contrary.
FIFA's disciplinary chief Claudio Sulser has said the Liverpool striker would be allowed to have a medical ahead of any transfer but the world governing body has stressed he cannot train with a team.
A FIFA spokeswoman told Press Association Sport: "As said at various occasions he is not allowed to participate in any football activity during the ban period and as such is also not allowed to train with the team during the ban."
Uruguay striker Suarez has appealed against the four-month ban imposed for biting Italy's Giorgio Chiellini.
Liverpool remain in talks with Barcelona over the transfer of Suarez, and Sulser on Friday told a news conference that the player would be allowed to have a medical ahead of a transfer.
Sulser said: "The player cannot have any activity related to football, but a medical examination for a transfer yes - the sanction is not linked to transfer rights."
Italian player Giorgio Chiellini has tweeted Luis Suarez 'it's all forgotten' after the footballer made a grovelling public apology for biting him during their opposing team's World Cup game.
.@luis16suarez It's all forgotten. I hope FIFA will reduce your suspension.
Luis Suarez has issued a statement on Twitter, apologising to Giorgio Chiellini and the "entire football family" for his bite on the Italy defender and promising "there will never again be another incident" like it.

Sportswear giant adidas says its 'reviewing all marketing activity involving Luis Suarez'.
The Liverpool striker has been banned from all football for four months after being found guilty of biting for the third time.
Suarez's boot deal with adidas could be in jeopardy after the sportswear manufacturer announced on Thursday that it would consider its partnership with the 27-year-old, who has returned to Uruguay after his World Cup accreditation was withdrawn.
His contract with 888poker was terminated on Friday.
Diego Maradona has attacked Fifa's ban on Uruguay and Liverpool striker Luis Suarez as "criminal" and said world football's governing body might as well handcuff the striker and lock him up in Guantanamo prison.
Maradona, who made to comments during his soccer commentary programme broadcast on Venezuela's Telesur and Argentine public television on Thursday night, asked: "Who did Suarez kill?"
The Argentine footballing legend added: "This is football, this is contact.
"They may as well handcuff him and bring him to Guantanamo directly.
"If he made a mistake, fine, they should punish him, but they shouldn't exaggerate, they shouldn't be moralistic."
Maradona, who like Suarez rose to fame from a poor background, fervently defended Suarez throughout the programme and unveiled a T-shirt with the words "We're with you Luisito" scrawled on the front.
Italian defender and victim of Luis Suarez's latest bite Giorgio Chiellini has spoken for the first time since FIFA confirmed it's ban on Thursday. The Liverpool striker was handed a four-month suspension from all football and fined 100,000 Swiss Francs:
"Now inside me there's no feelings of joy, revenge or anger against Suarez for an incident that happened on the pitch and that's done. There only remain the anger and the disappointment about the match," reads a statement from Chiellini on his own website.
"At the moment my only thought is for Luis and his family, because they will face a very difficult period.
"I have always considered unequivocal the disciplinary interventions by the competent bodies, but at the same time I believe that the proposed formula is excessive.
"I sincerely hope that he will be allowed, at least, to stay close to his team mates during the games because such a ban is really alienating for a player."
One of Luis Suarez's sponsors has dropped its relationship with the Liverpool striker.
