Hamsik is only 22 but that hasn't stopped Slovakia coach Vladimir Weiss describing the classy midfielder as "crucial" to his team's chances at this summer's World Cup.
There's a lot of pressure for Hamsik to perform but having made a real name for himself with Napoli in Serie A over the past three seasons, he's certainly ready for his first taste of a major international tournament.
The Slovakian midfielder's playing style has been compared to that of Chelsea and England's Frank Lampard as he likes to raid forward in search of goals, and even finished up as the Italian club's top scorer in his first two campaigns at the Stadio San Paulo.
Hamsik's first appearance for his country came back in 2007 and he's since gone on to earn 30 caps, notching eight goals and becoming the influential force behind their first ever qualification for a World Cup finals.
Having been made captain for the crucial 1-0 triumph over Poland in Chorzow back in October, Hamsik impressed with his strong character and leadership qualities as they sealed the result which guaranteed them a place in South Africa.
Hamsik's form for both club and country has led to him being linked with a number of Europe's richest clubs including Manchester City and the World Cup will be the ideal opportunity for him to further thrust himself into the limelight.
