“We’re going to work very hard to build a strong team but we’ll have to make changes because the image of the other day is not what we want. We’ll have to work hard to recover our prestige,” he said.

“It’s a big challenge and it won’t be easy because Barca always demands the best of you, which is the way it should be.

“Barca are still the biggest club in the world. Now we have to work hard to make sure Barca gets back to where they should be. There is enough quality in the team to demand the best results and to win trophies.”

Koeman did not reveal which players he would seek to move on from the club, although he made it clear he only wanted to work with those who were fully committed.

“I don’t want to mention names, we have to look in the club’s best interests and make the best squad possible to try and win games,” he said.

“There are players of a certain age who you can start to doubt, although a player who is 31, 32 or even 33 is not necessarily finished, it all depends on your hunger and whether you want to give everything for the club.

“I only want to work with players who want to be here, and if they are not happy here then they should say so. I only want people who are going to give everything for Barca.”
