samuel was amazing at roma, whats you talking about
At Roma, Capello used 3-6-1 formation, which is charactarised by having three defenders in the centre and a strong defensive supply form the midfield. It is a defensive tactics, even below average defenders would puzzle some people, as they might consider that the greatness of such a defensive performance is related to the defenders, whereas in fact it is all related to the tactic itself. Even though, Roma had a strong squad when they won the Scudetto; Candela, Cafu, Lima, Panucci and Zebina (he was in a good form). All the previously mentioned players are defenders and Samuel was just part of the whole performance.
By the way, Zebina was included in that squad, would you say that Zebina can be great once again?
And let's suppose that all what I did say is untrue, for a player to be great for just one or two seasons, could we even rate him for the greats? I don't think so.
