It comes after a public stand-off between Messi’s camp and Barcelona over the legality of his contract.
However, the 33-year-old has taken a step back to avoid a messy situation that could have led to a court case.
In his statement, Messi confirmed that he is unhappy at Barcelona and believes club president Josep Maria Bartomeu went back on a promise to let him go.
“I thought and was sure that I was free to leave, the president always said that at the end of the season I could decide if I stayed or not,” he said.
“Now they cling to the fact that I did not say it before June 10, when it turns out that on June 10 we were competing for La Liga in the middle of this awful Coronavirus and this disease altered all the season.
“And this is the reason why I am going to continue in the club. Now I am going to continue in the club because the president told me that the only way to leave was to pay the €700 million clause, and that this is impossible.
“It was a very difficult year, I suffered a lot in training, in games and in the locker room. Bartomeu has always told me that at the end of the season I could decide whether to stay or leave, but he hasn’t kept his word.”
No court case
He added that the alternative was a court case, something his love of Barca would not allow him to do.
He said: “There was another way [to leave] and it was to go to trial. I would never go to court against Barca because it is the club that I love, which gave me everything since I arrived.
“It is the club of my life, I have made my life here.
“Barca gave me everything and I gave it everything. I know that it never crossed my mind to take Barca to court.”
Messi: Barca is a mess
Messi did not hold back with his views about the current state of Barcelona.
The Argentina said there is no project at Barca and hasn’t been for a long time now.
“Of course I had a hard time deciding,” Messi revealed. “It does not come from the Bayern result, it comes from many things,
“I always said I wanted to end here and I always said I wanted to stay here. That I wanted a winning project and to win titles with the club, to continue expanding the legend of Barcelona.
“And the truth is that there has been no project or anything for a long time, they juggle and cover holes as things go by. As I said before, I always thought about the welfare of my family and the club.”
City must wait
The Pep Guardiola-led club wanted Messi on a free transfer and were never going to meet his €700m release clause.
Messi will be out of contract next summer and will then be free to join City or any other club.
For now, he will continue at Barcelona… reluctantly and unhappily.
