The Argentine eventually remained at Camp Nou to avoid a court case, but will be a free agent next year.
Messi was a target for City and the feeling was mutual, with the iconic forward pushing for a move.
And in an interview with the Manchester Evening News, City’s COO Omar Berrarda has admitted they could try again.
“He’s the best player in the world, he’s the best player of his generation,” said Berrarda. “I think any club in the world would like to explore the possibility of him joining their team.
“It’s hard to guess what could happen. If you think back to those two weeks where everything played out at Barcelona, it’s almost impossible to guess what will happen next summer.
“Messi is a generational talent, he’s the best player in the world and probably an exception to potential investments that we’d do out of the ordinary but our planning has been done with this current squad and it is being considered with the current opportunities that we have.
“For every single position we have to be prepared because there can be so many things that can happen but at the same time I think we have the financial strength and system ability to make that investment [in a striker] when required.”
An uncertain future
Messi has grown disillusioned with the situation at Barcelona, both on and off the pitch.
A change at boardroom level could be the Catalan club’s best hope of keeping him beyond this season.
For now, he is focused on giving his best for the club he has spent his entire career with.
The 33-year-old was among the scorers in Barca’s opening day win over Villarreal last month.
Since then, he has started in both of Barca’s other league games against Celta Vigo and Sevilla.
