Barcelona president Josep Maria Bartomeu admits planning for life after Leo Messi is now underway.
Messi, 31, has scored 581 goals in 664 games for Barcelona.
"I know one day Lionel will say he's retiring," Bartomeu told BBC Sport.
"We have to prepare the club for the future.
"We are bringing great young players to the team because we need to continue this era of success. That's our responsibility.
"My mandate will be finished in two seasons. So I need to leave the club in a great position and tell the new president 'that's our legacy'."
