The Argentine has been officially unveiled at Camp Nou, bringing to an end his illustrious 10-year career at Etihad Stadium
Sergio Aguero has joined Barcelona on a free transfer following his departure from Manchester City.
The 32-year-old underwent a medical at Camp Nou on Monday before signing a two-year contract with the Blaugrana.
Barca moved for Aguero after City's decision to let the striker go at the end of his contract, bringing to an end his trophy-laden ten-year spell in Manchester.
