Collina: Ronaldinho's goal at Stamford Bridge impressed me the most

The retired referee was left in awe by the Brazilian's strike against the Blues, and wished he could have officiated a game at the Bombonera.

Former FIFA referee Pierluigi Collina revealed that Ronaldinho's goal against Chelsea in 2004-05 was the best he has ever seen.

The Brazilian attacker, currently on the books of Flamengo, scored Barcelona's second goal of the night with the outside of his boot in the Blaugrana's 4-2 loss to the Blues in the Champions League.
