Liverpool extended the Premier League title race with Manchester City to the final day of the season after recovering from conceding an early goal to beat Southampton 2-1 at St Mary's.
Joel Matip secured victory by unwittingly heading home the winning goal in the 67th minute on Tuesday, leaving Jurgen Klopp's team a point behind City with one game left for each team.
Both play that on Sunday, when Liverpool host Wolverhampton Wanderers at the same time as City are at home to Aston Villa -- managed by former Liverpool star Steven Gerrard.
City, a point ahead and with a superior goal difference, remain favourites but Liverpool's quadruple is still on - just.
Klopp fielded a largely second-choice line-up, with the game coming only three days after an energy-sapping FA Cup final against Chelsea that went 120 minutes before the Reds won a penalty shoot-out.
Despite the slew of changes, Liverpool dominated a passive Southampton team with nothing left to play for this season but still fell behind in the 13th minute when Nathan Redmond cut inside from the left and sent in a shot that deflected off James Milner and into the far corner.
Liverpool's players kept their composure and replied 14 minutes later when Diogo Jota laid the ball off to Takumi Minamino, who displayed quick feet before firing a rising shot inside Alex McCarthy's near post. The Japan forward was on loan at Southampton last season and hadn't started a league game since.
The rest of the match saw Liverpool camped inside Southampton's half but only managing to create half-chances. The atmosphere was starting to get tense when Liverpool scored what proved to be a fortunate winning goal.
A corner by Kostas Tsimikas was glanced on at the near post by Southampton forward Mohamed Elyounoussi, skimmed off the head of Southampton's Kyle Walker-Peters, hit the forehead of Matip and rebounded into the far corner beyond McCarthy's despairing dive.
"The guys are incredible," said veteran midfielder James Milner of the irregular starters who had been called into action.
He added: "It is a special group of players and a special football club. We fight to the end and keep going. All we can do is take it as far as we can.
"It shows how ready everyone is, how ready they are mentally. It is special and that starts right from the top with the manager."
On the final day he added: "We will try and win our game, it is all we can do."
