Stefano Pioli says Milan "scraped the bottom of the barrel" as they came from behind to seal a dramatic 3-2 Serie A win over Fiorentina on Sunday.
Hakan Calhanoglu struck 18 minutes from full-time to move the Rossoneri to within six points of leaders Inter, who have a game in hand after their clash with Sassuolo this weekend was called off after a COVID-19 outbreak at the club.
The result meant Milan equalled their record of 12 away wins in a single top-flight season and ended a run of three games across all competitions without a win.
That included a Europa League last-16 defeat to Manchester United, and Pioli acknowledged his side had to dig deep to bounce back from that setback.
"This was the most difficult game because we were coming off the disappointment of the Europa League," he told Sky Sport Italia.
"We had been playing every three days for many months and knew we had to scrape the bottom of the barrel for the remaining drops of energy to get it done."
Zlatan Ibrahimovic had earlier put Milan ahead to become the oldest player to reach 15 goals in a single Serie A season, aged 39 years and 169 days, and the striker insisted afterwards they are still very much in the title race.
Pioli agreed with the veteran Swede and said Milan will do everything they can to reign in neighbours Inter.
"Ibra is right to talk about the Scudetto because we were up there most of the season," he added.
"We're not that far away now and we have the quality to play every single game for a victory. Whether we achieve it is another matter, but we can certainly try.
"Naturally, we started the season with very different objectives, as we were aiming to be in the top four.
"Now we are there, we want it to be a positive campaign right to the end. I've always said there will be four very happy teams at the end of the season and three who won't be."
Pioli also highlighted the contribution of Ismael Bennacer after he was introduced for Sandro Tonali shortly before the hour mark.
The Algeria international completed 30 of his 31 attempted passes and enjoyed a pass completion rate in the opposition half of 95.2 per cent.
"I would agree that although Tonali and [Soualiho] Meite are doing well, Isma has some specific characteristics that work really well with our system," Pioli said.
"He'll go on international duty now and hopefully get some minutes in his legs so he'll make a big impact in the final push of the season."
Milan are next in action at home to Sampdoria on April 3.
