Cristian Ledesma claims Lazio are beginning to really believe that they can qualify for next year's Champions League.
Sunday's 4-1 win away to Catania meant they held on to fourth place and cut the gap with Inter to three points.
As fate would have it, Lazio travel to meet Inter on Saturday for a game that could prove decisive to their objective.
"The game was won by the entire team," Ledesma said. "We've been through a difficult two weeks. It took a performance of this nature.
"We are enjoying the three points and thinking about Inter. We'll go to Milan to get a result.
"We believe in the Champions League more. The results have been favourable.
"It's still tough, but luckily this year the season will be played until the final day. It's all open and that's a good thing."
