Ronald Koeman will be the new manager of Barcelona, says club president Josep Maria Bartomeu.
The 57-year-old, who is currently in charge of the Netherlands, is set to join the La Liga runners-up this week.
Speaking on Tuesday night, Bartomeu said: "Koeman is the one we've chosen. If nothing goes wrong he will be the head coach next season."
Former Netherlands and Barca defender Koeman flew to Barcelona on Tuesday to finalise a deal with the club.
There have been rumours that the team's star Lionel Messi could leave but Bartomeu said: "Messi wants to end his career at Barca, he has said that many times.
"I have spoken with Koeman and the pillar of our project is Messi.
"He has a contract until 2021, I speak a lot with Leo and more regularly with his father.
"He is number one in the world. There is no doubt that in Koeman's new project you can count on Messi."
Bartomeu indicated a squad overhaul was now going to take place.
"The renewal will be as deep as necessary," he said. "I decided to give this generation the opportunity for another year. Maybe it was time to start the renovation last year.
"There is money but Covid-19 has reduced income so we have to reduce payroll to be able to bring in new footballers.
"The easiest thing would be to resign but I am not doing it because of my responsibility to the club. It is not a club crisis. It is just a sports crisis, which we must fix."
Koeman, who played for the Catalan giants between 1989 and 1995 and helped them to four league titles and the European Cup, has a contract with the Dutch FA which runs until the 2022 World Cup.
Earlier on Tuesday, when the former Barca player was asked if he wanted to return as manager, he said: "I'd like to, but it'll only be confirmed once I've signed the deal.
"Until then, I cannot say any more about it - even though I'd like to."
Barcelona parted company with sporting director Eric Abidal on Tuesday, one day after relieving head coach Quique Setien of his duties.
The dismissals come after the club's humiliating 8-2 defeat by Bayern Munich in the Champions League last eight on Friday.
Meanwhile, Barca's German goalkeeper Marc-Andre ter Stegen, 28, will be sidelined for 10 weeks after an operation on his right knee.

Koeman is going to be given a two-year deal. He would have said yes to a one-year deal. He has been trying to get to Barcelona for a long while.
Former Tottenham manager Mauricio Pochettino was contacted and there were talks with him even though the chairman realised the fans wouldn't like him [as a former Espanyol player and manager].
Pochettino is a better option. There is no doubt about that.
But we're not talking about the real issue. Barca are a club that's in disarray with a debt that some calculate could be 700m euros and unable to move on because they spend 70% of their income on wages for the first team.
They have no clear idea where to go next, partly because they can't get rid of these guys and partly because they've got no vision.
