#1 Lionel Messi

Lionel Messi is unarguably the best Barcelona player of not just the 21st century but of all-time, while a genuine case can also be made to consider him the best to ever grace a field in any club, on any continent and in any era.
He owes his career to Barcelona making a decision to finance the medical bills to treat his growth hormone and the story of how then-director Carlos Rexach drafted his first contract on a paper napkin is one that has been immortalised.
Fans of the club would forever be thankful to the decision-makers who brought a sickly 12-year-old to the club and just four years later, he became the youngest player to make his debut for the first team.
Since then, it has been records upon records being broken by the Argentine maestro and a week would not be enough to list all the milestones attained by the six-time Ballon d'Or winner.
He currently leads the way in terms of goals (626) and assists (261) for the club, while his 34 major trophies won in his time at Barcelona are also more than anyone else has managed.
