Speaking to beIN Sports, Howard said: "I think they have spent money for Manchester United in certain places and, like, ultimately the criticism of the ownership from fans - of any club but if you look at Manchester United - it is oftentimes one-sided.
"The Glazers own the football club, and that, in turn, is a business. What I've always said, because I am the owner of a football club, is that when you spend your billions to own a business, then you have the right to run it in any way you want.
"Now that will ultimately prove good or bad business, for sure, but you have the right to run it the way you want and along with that comes criticism. But everyone understands that. I think they have spent, and I think you can take it a step further and look at other clubs. Everton are a mess, not because they haven't spent. They have spent a lot of money. In fact so much so they got docked points because of PSR.
"So I think the Glazers are spending money. When you look at the squad and the amount of money that was paid for the likes of Sancho and Ronaldo and all these players, the money was spent. Was it spent wisely? Well, I'm not sure the Glazers make those decisions. So there are other parts of that question that need to be answered."
