Jose Mourinho reckons any manager would find it easier managing Manchester United than they would Chelsea.

That, he says, is down to stringent Financial Fair Play regulations which restrict how much clubs are allowed to spend on improving and maintaining their squads.

In the latest financial results (2013/14) United were second in football's rich list as they posted revenue of £433.2m - over £100m more than seventh-placed Chelsea, who posted £324.4m.

That, regardless of Blues owner Roman Abramovich's reported £6bn fortune, effectively means United have more than £100m extra to play with when it comes to funding transfers and wages.

"Yes, it's easier [to manage United]," said Mourinho. "It was easier before at Chelsea, but it's more fun like this.

"More difficult of course. We sold a lot of players, not just Juan [Mata, who joined United last January]."

Chelsea host Louis van Gaal's in-form United on Saturday evening and Mourinho says it will be a tough test for his side, despite United suffering a minor injury crisis on the eve of the clash.

"Their squad is amazing in terms of numbers, players, experience, solutions," added Mourinho.

"I have on the big screen in my office, not the team I'm going to play against but the squad and all the options.

"This week, when I arrived in the room, for the first time, I realised what they have. I'm not saying it's the best squad. It's a very good squad."
