New Barcelona forward Luis Suarez admitted he was concerned for his future in the days following his four-month FIFA ban for biting Giorgio Chiellini but is now putting the saga behind him.
The Uruguayan provoked uproar at the World Cup over the summer after being found guilty of biting an opponent for the third time in his career during the South American side's clash with Italy.
He was initially banned from all football-related activity for four months, as well as nine international matches, although that did not stop Barcelona from making the 27-year-old their marquee summer signing from Liverpool.
Although the four-month ban stands, the Court of Arbitration for Sport has subsequently relaxed the "excessive" elements of the punishment, meaning Suarez can now train and play in friendlies for his new club and country, and the former Ajax forward is now keen to move on from the incident.
"I was really depressed and didn't feel like doing anything" - Luis Suarez
"Of course I was concerned - not just about the transfer to Barcelona but more for me as a person. But, as I've said, that's in the past now and I'm trying to concentrate on Barcelona," he said at his official presentation.
"I'm here to do important things at Barca. Everything that happens in the past, that needs to be forgotten.
"If I start thinking about everything I've gone through, I wouldn't be able to sleep."
Suarez, who had previously been banned for biting PSV's Otman Bakkel and Chelsea's Branislav Ivanovic, initially denied he had bitten Italy's Chiellini in Uruguay's 1-0 win, but then issued a statement later confirming his guilt.
Asked whether he should have apologised earlier, 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."
