Malcom Glazer and his family have been criticised by United fans since they bought United in a leveraged deal in 2005.
Kroenke said: “Since they took over they have won and they have increased revenues by a huge amount. If I was a fan of that club, I would go there and go ‘Wow!’ because how could you do it any better?
“We have a whole different philosophy I think in the States, maybe, but I think it’s time maybe for everybody to think a little bit.
“I think they ought to think about who invests in these clubs.
“He (Glazer) took money out of the club. So what? (LA Lakers owner) Jerry Buss takes money out of his club. A lot of owners in the US do. No-one ever says anything about it.
“Did the Lakers win anything? Well, yeah. They did. How big’s their revenue? Pretty darn good.”
