Liverpool manager Jurgen Klopp has said his side must show an immediate response after a weekend defeat at Manchester United that felt "massively rubbish."

Following the 2-1 loss at Old Trafford, Liverpool trail second-placed United by five points with eight games remaining in the battle for the runners-up spot.

Liverpool take on Watford at Anfield on Saturday before there is a short break for international fixtures.

"We have to respond, 100 percent," Klopp told the club's official website.

"But in the moment I cannot, and I don't want to, think about anything else. I still have to work to swallow this one and it's quite difficult."

Klopp lamented the errors that led to Marcus Rashford's double inside 24 minutes at Old Trafford, but felt his side's second-half performance could have brought a draw.

"It's really difficult to take," he added. "The mistakes were obvious -- around the second balls we were not there and we cannot leave Dejan [Lovren] alone in the challenge there and nobody's around for the second ball. It doesn't work like this.

"Before the two goals, after the two goals, I thought we were dominant. We don't ignore the goals we conceded, but if you ignore them for a second you would say: 'OK, that's how you have to play.'

"I think with all the minutes around the two goals we conceded then a draw would have been deserved for us, but because we made these two mistakes we have to take the result like it is.

"It feels massively rubbish and that's not nice. We will carry on, of course, but in the moment it's a big disappointment."
