Stephan Lichtsteiner is confident Lazio have what it takes to qualify for next year's Champions League.
The Aquile currently lie third in Serie A, seven points behind League leaders Milan.
"Sure we believe that we can reach the Champions League," Lichtsteiner said.
"The most important thing is that there is no pessimism inside the dressing room.
"What happens on the outside doesn't interest us. We have a winning mentality even in moments of difficulty. It's something we didn't have in the past.
"This year we have already found obstacles and still managed to get points.
"We are certainly more united that we were before."
