Lazio coach Edy Reja has hailed the form of Chievo Verona this season.
The Romans face Chievo today.
"Chievo are without doubt the revelation of this season so far. They have won in difficult arenas like Genoa and Napoli, so we've got to be very wary.
"Even if we too are going through a fine period of form, on Sunday it will be a battle.
"We are going to Verona in order to win and I have faith, as my team is playing good football with humility and ever-increasing confidence," continued Reja.
"Sergio Pellissier is one of the most dangerous strikers in Serie A. I wanted to take him to Napoli a few years ago, as he is a great forward.
"It is also true that Chievo have excellent quality in the middle of the park. Besides all that, we have got to above all concentrate on our own performance, doing things well to make the most of every scoring opportunity."
