Gill: United singled out
Manchester United chief executive David Gill claims the FA singled out the club for "harsh" punishments which would not have been imposed on their Premier League rivals.
United found themselves involved in two high-profile disciplinary hearings last season.
Wayne Rooney was banned for two matches for swearing into a TV camera during the team's victory at West Ham in April, and Alex Ferguson was handed a five-game touchline ban for comments made about referee Martin Atkinson.
However, Gill believes similar punishments would probably not have been meted out to other clubs.
"I do genuinely believe there have been some poor-ish decisions that, in my opinion, wouldn't necessarily have hit other clubs," United's chief executive said.
"That's not to say I'm condoning Wayne's comments, because I don't think they were correct, or what Alex said. But at the same time, the actual punishments were harsh.
"We're possibly being caught up in being one of the biggest clubs and the (FA's) Respect agenda being there. What better way to demonstrate the authorities are being tough than by hitting one of the biggest clubs the hardest?"
