Manchester City have ruled out selling Sergio Aguero
Argentina striker Aguero was dropped by Pep Guardiola following the mid-season arrival of Gabriel Jesus and he fuelled uncertainty about his future by saying he would have talks with the manager at the end of the season about his role.
But Aguero finished the season strongly and Al-Mubarak has rubbished suggestions that City would contemplate selling their leading goalscorer.
“Is Aguero staying? Absolutely. There’s never been a doubt about that. I’ve read a lot of the speculation on this and it’s ridiculous,” he said.
“Sergio Aguero is one of the best players in the world. We are a team that aspires to win every competition we compete in.
"Having Sergio Aguero as part of the squad is an absolute must. It has never been in doubt.”
Al-Mubarak also admitted the club’s first season under Guardiola was a “disappointment” and that finishing third is “nothing to celebrate.”

Sergio Aguero scored 33 goals for Manchester City this season
But despite a rare trophy-less season, he remains confident the club is going in the right direction and believes Guardiola will be successful when he assembles the squad that can play the way he wants.
Manchester City finished 15 points adrift of champions Chelsea and five off Tottenham, and were knocked out of the Champions League in the round of 16, the FA Cup in the semi-finals and the League Cup in the third round.

It was the fact that their title challenge petered out so early that dismayed Al Mubarak who, in his end of season review, said: "There's nothing that annoys me more than people either calling me or sending me a message congratulating me on third place.
"My answer was pretty standard to everyone, 'don't congratulate me on getting third, there's nothing to congratulate, only congratulate me if we win the league'.

"So, this is not the ambition, not at all. There's nothing to celebrate. I think it's something which is important, it's critical, and I know it requires a lot of hard work, particularly in this league, to be in the top four, but our ambition is to win the league. And if not winning it, to go as close as physically possible to winning the league.
“Not being within close range of winning the title is no doubt a disappointment, not winning either the FA Cup or the League Cup is also I think a disappointment.
“We are team now that expects to win every year at least one trophy. And then to go further every year in the Champions League. So from that perspective the season has been a disappointment but if you look at it from a different lens we are truly going in a direction that is positive.
Manchester City have reaffirmed their commitment to backing Pep Guardiola
“I am very excited about how we are developing as a team, how Pep has taken the squad and really started a process of going through that natural cycle of development.
“We’ve gone through several cycles over the last nine years and we’re in the middle of one now but you can see where we’re going. I have high confidence that we are going in the right direction. You’ve seen many glimpses of us playing a type of football that is very exciting and very entertaining that I think the fans will grow to love and the results will come, I have no doubts the results will come.”
“Pep has introduced a new way of playing for us, an exciting way but a way that requires work and which requires a set of players that I think function within that system and probably ff I look back at this season that puzzle wasn’t complete and I hope this summer we support Pep in competing that puzzle.”
