Lazio boss Edy Reja admits that it will be emotional when he leads his team out against Napoli at the San Paolo this weekend.
The veteran tactician spent four years at Napoli and led the club back into Serie A with back-to-back promotions.
"The experience at Napoli completed me," Reja said. "It will be a great emotion for me at the San Paolo on Sunday.
"The Napoli fans like me a lot and I like them. It will be a really special day for me.
"As for Lazio, it will be very tough. We have a lot of players out. Napoli are travelling on the wings of enthusiasm.
"We have to try and come away with a positive result. It's a tie for the Champions League."
