Lazio coach Vladimir Petkovic is fully focused on their derby with AS Roma.
Petkovic was delighted with their 3-0 Europa League victory over Panathinaikos on Thursday.
He said: "It wasn't a high tempo, but Radu looked solid and he is certainly an option for the derby. We have to play like Lazio and not think about how Roma are set out.
"From the first day I got here the talk has been about the derby, as everyone urged me to win it. We are playing for three points, but they are certainly worth their weight in gold."
