The Premier League giants have moved to increase season ticket prices by around five percent.
While fans are unhappy at the change during a cost of living crisis, Al Mubarak outlined the reasons.
"This is a very delicate issue for sure. I appreciate the feelings of our fans when it comes to a very important aspect, which is the price of a ticket," stated Al Mubarak.
"I want to try to explain this very difficult balance that there is always tension between investing, growing, meeting more demand, being sustainable and financially viable, and at the same time, taking care of our core fan base and making sure they have affordable tickets and they continue to enjoy their football in the way they always have.
"We need to find ways to generate capital and revenue. Every pound coming out from that revenue has been reinvested in the team and continues to be reinvested in the team. So we have to again carefully tread.
"We're talking very closely to our fan base to make sure that we're able to strike that balance in an appropriate way. It's a balance. I recognise some of our fans obviously are not satisfied on the pricing side of it. We have to find solutions for them. That is our job.
"We have to work this out, but we also have to grow and we have to find the right commercial avenues for the club to continue to grow and to generate revenue, which inevitably then comes back to support the team and support the success that you've seen and that you will continue to see.”
