Striker Luis Suarez met Barcelona fans at a presentation in Barcelona on Monday.
Coach Luis Enrique says he plans to let Suarez debut at a friendly on Monday, while the player completes his competitive-match ban for biting.
Suarez was cleared last Thursday to play friendlies for Barcelona after the Court of Arbitration for Sport softened FIFA's decision to ban him from all football activities for four months.
Barcelona hosts Mexican club Leon on Monday in the Joan Gamper Trophy match.
It is a friendly the club traditionally uses to present its team for the forthcoming season.
