Gangwon FC mounted a nearly impossible five-goal comeback to beat Pohang Steelers in their K-League clash - with three goals coming in injury-time.

A Wanderson Carvalho double gave the visitors a comfortable lead and victory seemed assured when Lee Seok-Hyun added a third and Carvalho completed his hat-trick on 57 minutes.

It took another 14 minutes for Gangwon to strike back, firstly through Jae Wan-Cho and then former Arsenal and Tottenham youth-team defender Valentinos Sielis with 10 minutes to play.

Even as the game entered injury-time, seventh-placed Pohang appeared set for a comfortable victory - until Wan-Cho headed in from close range then smacked home a volley to level.

The best was yet to come, as Gangwon had appeals for a penalty denied then, when the subsequent corner was half-cleared a flying header from substitute Jung Jo-gook sealed victory.

Fans went mad for the unlikely comeback, with one Twitter user calling it 'one of the most iconic collapses ever in the K-League'.

Another drew comparisons with Liverpool's unlikely Champions League semi-final comeback against Barcelona which the Reds won 4-3, stating 'Lol Liverpool v Barcelona who?'
