Manchester United director Richard Arnold has defended the impact of the Glazer family on the club.

United group managing director Arnold has rejected accusations that the Glazer family's ownership has harmed the club.

"The various mechanisms we use to listen (to supporters' groups) are wide and broad," he said. "They would have their view, I wouldn't agree with it. I think a very long-term view has been taken.

"We work very hard to do our best at being a very well-run club and a lot of work has gone into engagement and other activities. It stands on its own.

"We listen to fans, be it on Facebook, Twitter, conducting surveys - we survey 80,000 fans in 60 countries around the world once a quarter to make sure we keep up to date on the opinions and how they're done.

"It's very important that there are fans' groups. Some have a high profile, some are unknown, but we're listening to those.

"The ultimate challenge for football club directors is balancing up those views."
