Javier Mascherano has described his move from Liverpool to Barcelona as "the opportunity of a lifetime".
The Argentina midfielder signed a four-year deal with Barca on Monday night after successfully undergoing a five-hour medical.
He was unveiled to the fans at the Nou Camp and then spoke to the press, and could not hide his delight at joining Pep Guardiola's hugely successful side.
He said: "I know that they've won everything, it's a team full of great players, with a base of world champions and I will try to be humble and help the team continue winning things.
"I'm going to have the chance to play with players who I admire and I will be able to say that I've grown and that I've been a better player at this club.
"This is an opportunity of a lifetime. I will train to be ready when I'm needed."
