Former AS Roma defender Christian Panucci sees an improvement in the character of coach Zdenek Zeman's team.
"To play at Roma you need personality and they both seem to possess a lot of it. Piris I thought was a bit tired, he's definitely faster than what we saw last night. Castan is a great central defender, perhaps a bit cumbersome coming forward, but he began very well.
"It is impossible to judge after a single game, we will have to watch the coming matches to understand the real value of these players."
