There is no football fan in the world that doesn't love a good comeback.
Unless your side is on the receiving end of one, it is simply one of the most thrilling aspects of any sport - particularly the beautiful game.
Liverpool's 4-0 win over Barcelona on the back of a 3-0 first leg defeat was one of the greatest ever witnessed.
Then the following evening, Tottenham produced arguably an even better comeback, beating Ajax 3-2 after trudging out for the second-half 2-0 down.
While those two results will live long in the memory, South Korean side Gangwon may have produced the most ridiculous comeback in football history.

- Barcelona considering re-signing Dani Alves
- Neymar tells Barca players he's coming back
It won't be broadcast throughout the world, but the K-League side actually came from 4-0 down to beat Pohang Steelers 5-4.
They were 4-0 down on 71 minutes, before Jae-Wan Cho scored what everyone in the stadium thought was a consolation.
Valentinos Sielis then added another on 79 minutes, but as the big 90 approached, Gangwon were still 4-2 down.
But six minutes later, they were 5-4 up.
Cho scored in the second and fourth minutes of injury-time, before Jung Jo-gook scored the winner in the 96th minute.
Imagine being a Pohang fan going into work on Monday morning...
The only comeback in the history of the Premier League that comes close to Gangwon's miraculous effort was Newcastle's famous 4-4 draw with Arsenal.
Arsene Wenger's side raced into a 4-0 lead at St James' Park, before Abou Diaby was sent off.
A brace of penalties from Joey Barton, a strike from Leon Best and a wonder-goal from Cheick Tiote in the final minutes completed one of English football's most memorable games.
So if you need a shoulder to cry on Pohang fans, the Gunners faithful kind of know what you're going through right now.
