The 33-year-old, who has scored a remarkable 635 goals in 735 matches for the Catalans, sensationally expressed his desire to leave the club in the summer - a move which was rejected by the board.
Barca chiefs insisted any suitor would have to pay his £630million release clause, a move which has seen Messi reluctantly decide to see his out the final year of his contract.
However, according to Daily Star, Manchester City are considering a January bid as Pep Guardiola looks to reunite with the Argentine superstar.
Messi has become synonymous with Barca for more than a decade, helping the club win four Champions League crowns, ten LaLiga titles and many other trophies.
And City's chief operating officer, Omar Berrarda, recently admitted that the Etihad giants will once again be ready to move in next summer.
