The former Blaugrana defender has denied that the Argentine is declining ahead of Sunday's Clasico with Real Madrid
Accusations that Lionel Messi is in decline are laughable, according to the attacker's former Barcelona team-mate Gianluca Zambrotta.
Messi endured a difficult match against Juventus in the Champions League on Wednesday, firing five shots off target as Barca exited the competition at the quarter-final stage, losing 3-0 on aggregate.
But Zambrotta insists Messi's form is not slipping, comparing the Barcelona star to his great rival Cristiano Ronaldo, who scored five goals in Real Madrid's 6-3 quarter-final win against Bayern Munich.
