English football champions Liverpool FC have suffered their fourth defeat in a row in the Premier League.
In the local derby against FC Everton, coach Jürgen Klopp's troubled team lost 2-0 (1-0) on Saturday.
It was also the Reds' fourth home defeat in a row - the last time it happened almost 100 years ago in December 1923 - and the first win for Everton at Anfield in over 20 years.
After a few minutes Everton took the lead through Richarlison (3rd).
The former Hoffenheim Gylfi Sigurdsson (83.) made a penalty for the final score after Dominic Calvert-Lewin was fouled by Trent Alexander-Arnold.
The narrow decision on the penalty kick was confirmed by the video referee.
Liverpool slipped further into the crisis.
The champions, who won 2-0 against RB Leipzig in the Champions League during the week, revealed similar problems as in previous league games.
Although the Klopp-Elf controlled the ball, it was too seldom dangerous and repeatedly showed weaknesses in defense.
Liverpool are sixth with 40 points, followed directly by rival Everton on points.
Historic bankruptcy: the Liverpool team before kick-off
Klopp's German coaching colleague Thomas Tuchel, however, remained undefeated with Chelsea.
However, his blues with the German national players Timo Werner and Antonio Rüdiger in the starting eleven did not get beyond a 1-1 (0-1) at FC Southampton.
Three days before the first leg of the first leg in the Champions League against Atletico Madrid, which will be played in Bucharest, Mason Mount (54th) gave the Tuchel-Elf a point with a penalty in Southampton.
Kai Havertz was not in the squad due to injury.
The hosts had previously taken the lead at St. Mary's Stadium with a goal from Liverpool loaner Takumi Minamino (33).
The team of former Leipzig coach Ralph Hasenhüttl could have taken the lead again in the second half, but Jannik Vestergaard headed the ball in the 74th minute to the crossbar.
In the Premier League table, Chelsea initially stayed in fourth place.
Liverpool missed the chance to overtake the Blues with a clear win against Everton or at least to draw level with their rivals for a Champions League spot on points.
Everton are now level on points with Liverpool.
Chelsea could be overtaken by West Ham United on Sunday with a home win against Tottenham Hotspur.
