The 47-year-old insists his side will treat their second-leg match like a final, but has pointed to rivals Galatasaray's 3-2 win over Real Madrid as proof that the tie is not over
The Turkish side take a 2-0 first-leg lead to Stadio Olimpico on Thursday evening, and although he considers their advantage from last week to be important, Kocaman has pointed to Galatasaray's Champions League clash with Real Madrid on Wednesday as proof that their lead could be vulnerable.
"We want to write history by qualifying for the semi-final for the first time," he told a press conference. "After the Galatasaray game we saw that anything can happen in football, but we do have self-belief before the game. We want to use the advantage of the first game."
The meeting will be played behind closed doors as a result of Uefa sanctions against Lazio following repeated racism from supporters, and while he condemns the actions of those responsible, Kocaman claims his side will use the empty stands to their advantage.
"It [racism] is a shameful topic for humanity to talk about," he continued.
"This time playing without supporters will be to our advantage. We'll play tomorrow like a final game."
