Liverpool manager Jurgen Klopp has called on his defenders to tighten up after his team was bundled out of the FA Cup by Chelsea on Tuesday.
It was the second loss for The Reds on the trot following their Premier League loss to Watford on Saturday but Klopp said he was not too concerned by a run of just one win in four outings.
"Look, it went our way for so long because we defended outstandingly. Usually, you don't get a lot of chances against us and stuff like this, but now we have to admit that in the last three games (maybe) four, we have conceded absolutely too many goals, that's true.
"I am not worried about the momentum-momentum is not something you get as a present, you have to get it to keep it. We have always a chance to get it back.
"I am not concerned about the momentum, but it is football and we never thought it would be an easy season, it would be an easy period, it would be an easy game tonight. Nothing, it was always clear it would be difficult-it was always clear it was difficult.
"We did very well, but tonight not good enough in decisive moments and that's what we have to accept," Klopp said after the game.
The Reds went down 2-0 at Stamford Bridge, an error from Adrian allowing Willian to open the scoring before Ross Barkley added a second after the break.
Liverpool had also lost 3-0 at Watford on Saturday, their first reverse in the Premier League this season, and have now conceded two or more goals in three consecutive matches for the first time since 2016.
