Messi tried to force a move away from Spain last summer but ended up staying at Camp Nou.
However, the 33-year-old is set to become a free agent at the end of this season.
Barca has grown increasingly confident of keeping Messi beyond this summer, following an upturn in results and Laporta’s return last month.
However, Messi will not put pen to paper until he can see clear progress is still being made on and off the field.
He also expects Barca to make astute signings, such as Eric Garcia on a free transfer from Manchester City, plus one marquee signing – possibly Borussia Dortmund star Erling Braut Haaland.
Messi is also said to have made it clear to Barcelona, that more needs to be done to integrate younger players into the first-team fold, and he would like to retain a direct line of communication with the club’s president.
