The Argentine and the Barcelona board, specifically president Josep Bartomeu, became embroiled in a bitter public dispute after Messi sent a letter informing them of his desire find a new club.
The 33-year-old admitted he had wanted to leave "all year" and claimed a clause in his contract meant he could do so for free, but in the end the Argentine was forced to stay as Barcelona disagreed and wasn't willing to reduce its €700 million ($897 million) release clause.
Messi said his love for the club meant he had no intention of disputing the club's decision in court and dragging out a legal dispute.
"Uniting passion with excitement and motivation will be the only way to achieve our objectives, always united and rowing in the same direction.
"I wanted to send a message to all the socios and fans that follow us. If at any moment, any of them were annoyed by something that I said or did, let there be no doubts that anything I did was always with the club's best interests in mind."
