Liverpool's recent run of positive results is "insane", boss Jurgen Klopp said after they made it 14 Premier League games unbeaten with victory over Everton in Sunday's Merseyside derby.
The Reds trail leaders Manchester City by a point, having dropped just four points in the league since 28 December.
They are in contention for a quadruple, with a Champions League semi-final and FA Cup final to come.
"The amount of wins we've had in recent months is insane," Klopp told the BBC.
"You have to work. The boys did that again. I'm really happy."
It is now 13 wins in 15 league games for the Reds since their loss at Leicester just after Christmas, with recent results also including them beating Pep Guardiola's City in an FA Cup semi-final and Benfica over two legs in the Champions League last eight. They also won the Carabao Cup in February.
Klopp's side were frustrated by a stubborn Everton in the first half of Sunday's game at Anfield, but a header from Andrew Robertson broke the tension before Luis Diaz set up fellow substitute Divock Origi to score his sixth Merseyside derby goal to seal the points.
"Thank God the game has two halves," German Klopp said. "We didn't play particularly well in the first half. They made it uncomfortable but we didn't get in behind the last line. We didn't have enough movement.
"We weren't quick enough. We passed the ball into the area they had nine players. Second half we were much more direct and caused them much more problems.
"We stayed really cool and calm. The changes helped, fresh players, different formation. It made it difficult for the opposition.
"We won 2-0, it's absolutely fine."
