Here are Messi's most Iconic Moments:
Messi nets 91 goals in a year
Even by the remarkable goalscoring exploits of Messi and Cristiano Ronaldo, the Argentine's star managed to score 91 goals within a year.
He netted 79 goals for Barcelona and 12 for Argentina, during 69 games for club and country.
It was enough to earn Messi an unprecedented fourth consecutive Ballon d'Or - even though he only won the Copa del Rey in 2012 for all those goals.
Messi's first hat-trick
Messi's first career hat-trick came in the 2007 Clasico as the teenager scored all of Barca's three goals in a 2007 Clasico, including a brilliant last-minute finish after beating a couple of defenders.

In a goal with remarkable similarities to Diego Maradona's (non-handball) strike against England in the 1986 World Cup, Messi picked the ball up in his own half, beat about five defenders, went round the goalkeeper and then slotted home.
Messi's first Champions League final goal
If you can believe it, there was a time when people questioned whether Messi could do it against English clubs in Europe. He had failed to score in 10 Champions League appearances against English sides before the 2009 final.
But there were no doubts any more when Messi rose highest in the box to head home Xavi's cross in his first Champions League final - and the first game billed as Messi v Cristiano Ronaldo.
Two years later he would score in another final win over United - the third of his four Champions League winners' medals.
