In one of the most remarkable matches in Premier League history, Liverpool came from 3-1 down to lead before overcoming an injury-time equalizer to secure a thrilling 5-4 win at a crestfallen Norwich City. The full drama quota at Carrow Road looked to have already been fulfilled when Liverpool, who had taken an early lead, went from 3-1 down to 4-3 in front in the space of 20 second-half minutes. But the real excitement was yet to come.

Liverpool manager Jurgen Klopp was still fuming on the sidelines about the five minutes of injury time that had been added when Norwich defender Sebastien Bassong drove home a shot from 20 yards that found the back of the net. The Carrow Road crowd, which had been silenced by Liverpool's fight back, were suddenly jubilant at the prospect of a valuable point in their battle against relegation.

Instead, in the fourth minute of injury time, Adam Lallana brought an end to a penalty-box scramble by firing home a left-footed volley to secure Liverpool a most unlikely three points. For the former Southampton midfielder, it was by some way the highlight of a Liverpool career that has yet to catch fire. And he duly celebrated in style, whipping off his shirt and running to the touchline, when he was met by his equally ecstatic manager, who had gone from the depths of despair to the heights of elation in a matter of moments.

In contrast, Norwich goalkeeper Declan Rudd could only fall to his knees in a sign of utter despondency. This was definitively not a game for the two goalkeepers to shine. Perhaps the most extraordinary statistic of all from the wackiest of games was that nine of the 12 shots on target had found the back of the net.

The result leaves Norwich just two places above the relegation zone, with the potential for them to fall into it before the weekend is out. Liverpool, meanwhile, temporarily at least, climb up into seventh place.

It had appeared that the afternoon might be a far more straightforward one when Roberto Firmino gave the visitors an 18th minute lead. Found in behind the Norwich defense by James Milner, the Brazilian, again leading the Liverpool attack, finished impressively with his left foot. But by halftime Norwich were in front. After Dieumerci Mbokani back-heeled the hosts level, new signing from Everton Steven Naismith grabbed a debut goal with a fine low finish from a tight angle on the right of the area.

And the Scotland international was involved, too, as Norwich extended their lead and appeared to have set themselves on the path to victory nine minutes into the second half. Liverpool defender Alberto Moreno was clumsy in the extreme in bundling Naismith down in the box, and Wes Hoolahan made no mistake from the resulting penalty.

At that point nobody could have foreseen what was to follow. Just a minute after falling 3-1 behind, captain Jordan Henderson started the Liverpool comeback with a low finish from 12 yards following a clever flick from Firmino. And just eight minutes later, Firmino himself pulled Liverpool level, capping a fine Liverpool move down the left by turning home Lallana’s cross.

Norwich’s misery appeared complete when captain Russell Martin’s errant backpass allowed Milner to run clear and put Liverpool in front with 15 minutes remaining. Yet, for the Canaries, worse was to follow in a match that turned from a regular thriller into a true Premier League classic.
