Inter Milan are preparing for Sunday's clash with Fiorentina knowing the match might be be rendered meaningless if AC Milan beat Roma at the Stadio Olimpico.
Leonardo said: "We're disappointed we weren't able to overtake all the teams that were ahead of us but the eventual winners always deserve to win.
"We gave it our all in games that turned out to be decisive, while dealing with the various problems Inter have had to cope with this year, and just trying to push on.
"It's been a long, hard slog of a season but, as I said, today we are still a very competitive team."
Inter, who have the second leg of their Coppa Italia semi-final against Roma on Tuesday, have three wins from their last four league games.
Fiorentina were 5-2 winners over Udinese last time out.
Serbian winger Stevan Jovetic will definitely miss out for the Viola while Adrian Mutu, Mario Santana and Marco Donadel are in with a chance of playing against Inter after training on Friday.
Jovetic, who has missed the whole campaign to date after injuring the cruciate ligament in his right knee in pre-season training, would like to have played but has been persuaded not to take any risks with the team safe in mid-table.
"If it was up to me, I'd be playing again now," said the 21-year-old.
"I've been waiting for eight months. But we must be careful - I have a contract until 2013 and still want to do great things with Fiorentina."
