Edy Reja insists Lazio can beat Inter next Saturday and maybe finish on the podium this season.
Sunday's 4-1 win at Catania means Lazio are now three points behind third placed Inter with five games of the campaign remaining.
Inter lost 2-0 to relegation threatened Parma at the weekend and appear to be tired.
Interviewed by Lazio Style radio this afternoon, Reja said: "Now we have to win everywhere starting next Saturday at San Siro against Inter.
"Recently Inter have not been doing very well. We hope that it stays that way on Saturday.
"Third place is close and now we have to try and catch the teams in front of us without looking back anymore."
