Christian Benteke returned to haunt Liverpool using a double as Crystal Palace took another enormous step towards ensuring Premier League security using a 2-1 triumph at Anfield.
Benteke levelled matters three minutes before the break and was presented with an easy header to complete the comeback win on 74 minutes, handing Sam Allardyce his first taste of success at Anfield in 12 league visits.
Liverpool old boy Christian Benteke haunted his old club, scoring twice after Philippe Coutinho had given the home side the lead. Yohan Cabaye laid the ball on a plate for Benteke and the Belgian smashed home from close range.
It is now five goals in his last five games for the tall Belgium striker, who equalized at Anfield in the 42nd minute with a sidefooted finish before stooping to head home the victor from a corner in the 74th.
Palace's sixth victory in their last eight league games handed Allardyce his first ever win at Anfield and the Crystal Palace manager explained how he aimed to exploit Liverpool's weakness at defending set pieces.
Liverpool won the reverse fixture 4-2 back in October.
Conversely it has opened up Liverpool, still in third, to the unpalatable prospect in these parts of being caught by Manchester United in the race for a top-four spot.
Jurgen Klopp's side started the second half brightly and Coutinho looked certain to get his second of the game when he went on a mazy dribble into the box, However, his eventual shot was blocked by the Palace defence.
"It is not sure that we will bring him [on] because Marko Grujic can play this position also, but we don't have a lot of options so that's our squad and everything is fine".
"When the ball is in the air he is the main threat because he is unbelievable and we felt it all the time in training when he was here", Klopp said.
It left them only two points ahead of Manchester City and three in front of Manchester United, who each have two games in hand.
Liverpool manager Jurgen Klopp is well aware of the threat Christian Benteke poses but has warned his players they can not concentrate their focus on the big man.
The Reds already have six more points this season than the 60 they amassed in the whole of last season, and are the leading scorers in the Premier League with 69 goals.
"If he goes down it's a penalty 100 percent", Klopp told Sky Sports News.
"He wasn't the same when he came back but now he is showing what he was at the start of the season, that he is one of the top players in the Premier League".
