Though Maradona is now retired, he is still considered as the greatest football player of all time by many experts, former players, critics, fans and current players.

This fact was officially confirmed when he was awarded FIFA Player of the 20th Century. He and Pele share this one-off award.

Maradona has several unique achievements in his bag including the only football player in history who set the world record transfer fee twice.

He became the coach of Argentina in November 2008 and was in charge of the team at the 2010 FIFA World Cup in South Africa.

As the legendary football player celebrates his 55th birthday today (Friday), here are five best moments from his football career.

Four goals against Boca Juniors (1980)

In an interview in 1980, prominent goalkeeper of Boca Juniors Hugo Gatti said, "Maradona is a 'gordito' [fat kid] who could play football very well." Maradona, who was in Argentinos Juniors back then, vowed to score four goals when the two clubs next have a match. He splendidly did so.

1986 World Cup win in Mexico

Argentina scored two goals in the second half of the game against West Germany and Maradona made a perfect through-ball in the last minutes of the game that earned Argentina the World Cup and him the Golden Ball.

The Hand of God

In 1986 World Cup quarter final against England, English midfielder Steve Hodge tried to loop the ball towards his own goal that prompted Maradona to get into an aerial duel with the goalkeeper Peter Shilton. With an instantaneous flick, Maradona lofted the ball away from Shelton and into the net.

Maradona as a Napoli legend

When Napoli defeated Milan in Coppa Italia double 1987, Maradona became God in the eyes of the peoples of Naples as it was also a victory for south Italy over their boisterous northern counterpart.

When Argentina defeated Brazil in world Cup 1990

With waning health as a result of taking drugs excessively, Maradona was left to be only the shadow of his former self in the 90s. However, just when fans were thinking his days were over, he proved them wrong by making an amazing run and pass to Claudio Caniggia and hence scoring the only goal of the match granting a victory to Argentina.
