Lionel Messi has been playing at the Camp Nou in Spain for 21 years, or more than half his life. However, for the first time in his professional career, the Argentine will be seen wearing a jersey that is not Barcelona's. The last time was back when he was still a promising 13-years-old talent at Newell's Old Boys in his homeland, Argentina.

While announcing his sudden and unexpected departure, Barcelona revealed that both sides had previously come to an agreement for a long-term five-year contract extension until 2026. Because of the Blaugrana's dire financial condition and La Liga's tight wage limit restrictions, Ronald Koeman's side will be significantly weakened as the superstar forward and the club have been unable to proceed with the new deal.

In the past 15 years, Messi has been the face of Barcelona and his bombshell exit is certainly a huge blow to the club's fortunes. It is trivial whether there was a chance for the 34-year-old to re-sign for the La Liga giants, as he is now on his way to join his former Camp Nou teammate Neymar at Paris Saint-Germain.
