Remarkable comebacks in sporting history

Liverpool vs AC Milan
25 May 2005 Champions League Final
Normal Time Score: 3-3
Liverpool won 3–2 on penalties

When they were 3-0 down at half-time I was just praying they wouldn't get mauled. From the way Milan played during the first half, the score flattered Liverpool. They had them by the balls. But who could've possibly predicted what happened later on. If Benitez's pep talk had any real effect then that must've been the mother of all pep talks, as they went back onto the field as if they were a different team and managed to overturn what many thought was an insurmountable lead. For me, this is a classic example of David and Goliath, Milan was better than Liverpool in virtually all aspects of their game, any of their players could grace the lineup of the great teams of the ages. But with belief anything was possible. From that point since being crowned champions, they went on to become one of the most feared teams in Europe. Nobody wanted to play them. No player wanted to experience the heartbreak that Milan went through. They almost pulled it off again a few years later with a tie against Chelsea, which shows the never-say-die mentality instilled into them.

Words can't ever truly explain the greatness of the match but this quote by Maradona is very on point:

"Even the Brazil team that won the 1970 World Cup could not have staged a comeback with Milan leading 3-0...I have seen comebacks like that in football but never against a team that so clearly was superior as Milan were."

Hey, esports count! ;) I've actually seen people come back from close to death against opponents with full health. But how many can pull off a full parry on a super and return it with a super of his own to end the round? It was both daring and cheeky at the same time like he was making a mockery of the turtle style.

Magpies vs Gunners
5 February 2011 Premier League Match
Score: 4-4

I think this one reveals the schadenfreude side of me. Even with the respect I have for Arsene Wenger and his contributions to the British game, I couldn't resist amusement with the faces they pull. It tickles me whenever a smirk is wiped away in an instant and replaced with a frown. The contrasting expressions couldn't be more opposing between the two managers at the end of the match.

Winner of 2001 Wimbledon Championships

The word "comeback" was written all over his fairy tale win at Wimbledon. The spotlight was on Henman, with papers touting that this was "his year." How many would have put faith on a has-been such as Ivanisevic, who only managed to sneak into the tournament as a wild card entry and even contemplated retirement. In their matchup, Henman was on the ascendancy from the get go and from then on it is really for him to lose. But somehow Ivanisevic found something within himself to turn it around with the aid of a rain delay. British hopes of a Wimbledon champion were really resting on Henman but it wasn't to be. It would take well over a decade before the hoodoo was finally broken.
