Jurgen Klopp acknowledged Liverpool are enduring a tough run but insisted performances have not been as bad as results suggest.

The defending Premier League champions are top of the table again but have won just two of their past six matches – and two of seven in all competitions.

Rivals Manchester United, who have a game in hand, have moved level on points with the Reds at the summit ahead of the two sides meeting next weekend.

"We were not waiting for [this run of form] and we do not enjoy it, but it's not unlikely that these kinds of things happen," Klopp told a news conference on Thursday.

"I think we only won two of the last six – that's not the standard we expect from ourselves, obviously.

"So, we don't take it easy, but we still see what we can improve, what we have to improve, and don't think everything was bad in the last few weeks.

"The league is too strong, and if you struggle a little bit, immediately the results go the other way because the opponents are fighting with everything they had. You saw that against Southampton [a 1-0 defeat on Monday]."

Liverpool must first focus on the FA Cup, however, with Aston Villa hosting Klopp's men in the third round on Friday.

Last season's run to round five was Liverpool's best under Klopp, with the Anfield outfit eliminated from four of their past six ties against fellow Premier League sides, only beating Everton (in 2018 and 2020) in this time.

The Reds had reached the semi-final in the final season before Klopp's appointment, losing to Villa in the last four to end a six-match winning run against Friday's opponents in the competition.

Despite his underwhelming record in the competition, the manager says Liverpool have always been determined to succeed.

"It's important. It's the FA Cup," he said. "We didn't go far so far in this competition.

"I didn't think we were blessed so far with sensational draws so far and now we go to Aston Villa, which is a tough one as well.

"We always took it very seriously and will do this time as well, but we cannot forget the intensity of the period we are in and all these kinds of things.

"It's important – football games are important. We are professional football players or coaches or managers and the only thing we have to do is to win football games and to try to make sure that we really can do that. It's a very important competition, so we will try to win that."

Liverpool were beaten 7-2 by Villa in the Premier League this term, shipping seven goals in a single match in any competition for the first time since 1963.

Klopp is therefore reluctant to name a weakened team, even with the United game on the horizon.

"We need to find the balance to field a team where we didn't change too much," he said. "We bring in fresh legs again.

"The rhythm [for returning players] is a different issue. That's step by step. We cannot do that in one game. We can't use the FA Cup to give players rhythm – the opponent is just too strong for that.

"After the Aston Villa game, we have eight days between Villa and Man United, so that's a long training week where we can do a lot of stuff in 11-v-11 situations, which will help the players a lot, especially the players who were out for a while. After that, we will be in a different place."

Pressed on specific injuries, Klopp added Naby Keita would return "soon" but not this weekend and Liverpool "will try" to have Joel Matip back for Manchester United, although Diogo Jota is still wearing a brace on a damaged knee.

Jurgen Klopp was, predictably, none too pleased after Liverpool lost 1-0 at Southampton on Monday.

Not only did the Premier League champions see a 12-game unbeaten run end, but they also gifted Manchester United the chance to go top of the table if the Red Devils win their game in hand.

Liverpool only managed one shot on target against Ralph Hasenhuttl's Saints after conceding a Danny Ings goal in the second minute, when a free-kick eluded Trent Alexander-Arnold and gave the former Reds striker the chance to score a fine lob.

Klopp admitted they should have done better with that set-piece, but he was further irritated in the second half when two penalty appeals were turned down, first for a tangle between Sadio Mane and Kyle Walker-Peters and then for a Georginio Wijnaldum shot that struck the arm of Jack Stephens.

"[The handball] looked like a clear penalty," Klopp said. "I turned to the fourth official, he said: 'We checked already, no penalty.'

"What [referee] Andre Marriner did with Sadio Mane tonight, I'm not sure that's okay, to be honest.

"I hear now that Manchester United had more penalties in two years than I had in five and a half years. I've no idea if that's my fault, or how that can happen."

It's quite the claim – but is it true?

PEN STATE

Under Klopp, Liverpool have been awarded 46 penalties in all competitions, including 30 in the Premier League (they've scored 39 of them, for good measure). In that same time frame, and under three different managers, United have won 67 and scored 54 penalties in all competitions.

What about the past two years? Well, 42 of those United penalties have come since Ole Gunnar Solskjaer became manager in December 2018, with 27 in the league. Liverpool have had just 19 spot-kicks in that time. Klopp, then, has a point.

If you combine the past two Premier League seasons, no team has had as many penalties as the Red Devils, who have won 20 and scored 15 of them. Next on the list is Leicester City (17 won, 13 scored) and then Manchester City (14 won, eight scored). Liverpool have won 10 in that time and scored every one.

Having half the number of their bitter rivals will doubtless be a source of frustration, but they should consider the feelings of Everton fans. The Toffees have had just three penalties in the past two seasons, the lowest of any side to be in the division across both campaigns.

SPOT THE DIFFERENCE

In 2019-20 in the Premier League, United won more penalties than anyone else (14 – three above nearest rivals Man City). That number was a record for a single season in the Premier League era. Liverpool won five.

The balance actually seems to be shifting a little in 2020-21, though. United are joint-second for Premier League penalties (six, level with Brighton and Hove Albion), but four behind Leicester, who won 10 spot-kicks in their first 16 games, a competition record.

Liverpool, for their part, are only one behind United on five. Had the Southampton game taken place in the first few weeks of the season, they may well have caught up with them through the Stephens incident: the earlier implementation of the handball rule led to seven such penalties being awarded in the first five matchdays of 2020-21.

Only five have been given since, and none since December 13 – when Fulham's Aboubakar Kamara was penalised against Liverpool.
