Jurgen Klopp says Liverpool need to find consistency to avoid missing out on a top-four finish in the Premier League after his side suffered a damaging defeat by struggling Leeds at Anfield.
Crysencio Summerville scored a dramatic late winner as Leeds won to move out of the relegation zone.
The defeat leaves Liverpool eight points adrift of Newcastle in fourth, albeit with a game in hand.
The Reds beat Premier League leaders Manchester City on 16 October but have since lost to bottom-of-the table Nottingham Forest and now Leeds.
"You can't qualify for the Champions League if you play as inconsistently as we do at the moment," Klopp said.
"We have to fix that."
Liverpool were hoping to build on their dominant 3-0 win at Ajax in the Champions League in midweek but they made the worst possible start against a Leeds side who started the day in the bottom three when a poor back pass by Joe Gomez was pounced on by Rodrigo, who poked into an empty net.
Liverpool responded well and equalised soon after when Mohamed Salah volleyed in from Andy Robertson's cross.
But Leeds, belying their lowly position in the table, showed great hunger in response to that equaliser and hit the woodwork through Brenden Aaronson.
Illan Meslier made great saves to deny Darwin Nunez one-on-one in the second half, before the Leeds goalkeeper also kept out a Roberto Firmino header.
And, in the final minute of normal time, Summerville picked up the ball from Patrick Bamford before firing across Alisson to send the away support wild.
The defeat - Liverpool's second in a row in the Premier League - means they are ninth while Leeds move up to 15th, four points behind the Reds.
