Mancini was a teammate of Seba's when Lazio won the Scudetto and Coppa Italia in 2000. And, despite Seba's unsuccessful spell in England thus far, Mancini is warning his players of Veron's danger.
He said "Chelsea have very good players, their attack is probably their most dangerous weapon. We have to pay attention to Veron, who I believe is one of the best players in the world, and we will have to be particularly aware of Crespo and Mutu.
"Chelsea are very strong on the counter-attack and we cannot afford to lose the ball."
It's going to be a real humdinger of a match tonight! Come on Chelsea!!
