Liverpool staged a second-half comeback against a resilient Norwich side to keep their Premier League title hopes alive with an eighth successive win in all competitions.
The Reds had threatened the Norwich goal countless times but they were stunned into emergency action moments after the interval when Milot Rashica's deflected strike gave the Canaries hope of a first win at Anfield in 28 years.
Liverpool boss Jurgen Klopp, who made seven changes to the side that won at Inter Milan in the Champions League in midweek, intervened to make attacking changes on 62 minutes and within four minutes his side had turned the game around.
Sadio Mane acrobatically turned home Konstantinos Tsimikas' header and Mohamed Salah raced on to a clearance from goalkeeper Alisson Becker to round Angus Gunn and score.

Salah's 17th league goal of the campaign was his 150th in all competitions for Liverpool - making him one of only 10 men to reach that figure for the club - and Luis Diaz added his first since joining from Porto with a neat, chipped finish to seal the win.
Klopp's side move to within six points of league leaders Manchester City before the champions' late game, while Norwich drop to bottom place and are five points from safety.
Hakim Ziyech scored a last-minute winner as Chelsea edged past Crystal Palace on their return to Premier League action.
Thomas Tuchel's side last played in the top flight almost a month ago when they defeated Tottenham, and have had a week's rest since winning the Club World Cup last Saturday.
Elsewhere, It looked like they would be frustrated by their hosts but Ziyech popped up at the back post to stroke in a delightful volley from Marcos Alonso's cross.
Moroccan Ziyech had converted earlier in the second half when he swept home following Jack Butland's save, but Romelu Lukaku was adjudged to be offside by VAR.
Vicente Guaita had made good saves in the first half from N'Golo Kante's effort and Antonio Rudiger's long range thunderbolt, before the Palace goalkeeper was taken off at half-time because of a knee injury.
The home side, meanwhile, did not have a single shot on target in the entire contest - both Michael Oliseh and Wilfried Zaha failing to work Edouard Mendy from promising positions.
