Barcelona could not show off their new signing from Liverpool because he is serving a four month ban from all football for biting Italian defender Giorgio Chiellini.
But sporting director Andoni Zubizarreta said: “Luis Suarez is going to play a positive role in the years he will be at Barcelona.”
“This is an important point although Barcelona is more important than one player, he added.
The Spanish giants “accept humans with all their imperfections, all their mistakes and their capacity to learn from their errors.”
“This is one of our values. Our history is full of good days as well as bad days,” Zubizarreta said.
The incident with Chiellini during Uruguay’s World Cup group win over Italy was the third case of Suarez biting an opponent.
Barcelona paid a reported EUR95 million ($128 million) for Suarez. But he cannot train or play with them until November because of the four month ban imposed by a FIFA disciplinary committee.
He was also suspended for nine internationals and fined 100,000 Swiss francs ($112,000).
A lawyer for Suarez has said the player will appeal against the biggest punishment imposed at the World Cup to the Court of Arbitration for Sport.
Asked if Barcelona wanted to get the ban reduced, Zubizarreta said: “We are analysing the information provided by FIFA to see how we can defend the player’s rights.”
He added that club lawyers had recommended that officials be “extremely prudent” when discussing the case.
Barcelona’s new coach Luis Enrique told the press conference he would have prefered to have Suarez ready at the start of the season.
“It’s bad that he’s not with us from the start, but it’s not a tragedy. Somebody else will play in his place,” he said.
Suarez was the top scorer in England’s Premier League last season with 31 goals.
His signing furnishes the Catalan club with one of the most formidable strike forces in the world as he joins two other superstar forwards — Argentina’s Lionel Messi and Brazil’s Neymar.
Enrique rejected the idea that Suarez’s arrival would disrupt the squad’s attacking system.
“The more top players they give me, the better. We have been reinforcing the squad and we are going to continue to do so,” he said.
FIFA president Sepp Blatter said Monday that Suarez’s ban was “very severe” but that he had to accept the action of the FIFA committee.
