Sir Alex Ferguson and Jose Mourinho's teams will potentially contest three crucial matches next month to determine the outcome of the Premier League, the FA Cup and - if Chelsea beat Liverpool in the semi-final - the Champions League.

Sports marketing experts believe that the value of being crowned kings of Europe will be more than £30million (approximately $AUD71,750,000)

Dominic Curran, director at sports marketing consultants Karen Earl Sponsorship, said: "From a commercial point of view, the Champions League is the one to win simply because of the global profile.

"If Manchester United or Chelsea have the Champions League in the bag when the time comes to re-negotiate with their sponsors then they are in a very strong position.

"The Premier League is huge across the world, but Chelsea have won it for the last couple of years while the Champions League is a rarity.

"After Liverpool won it a couple of years ago the rise in their value in terms of sponsorship was quite incredible."

In terms of prize money and TV cash, Chelsea and United both made around £29million from the Premier League last season, and can expect to earn the same again this time around.

The FA Cup will swell their coffers by a further £2.4million - with the winners of the first Wembley final taking home a further £1million.

In Europe, both clubs are guaranteed around £20million with a further £4million for making the final, and another £2million on top of that for winning it.

Curran added: "The TV money and prize money is one aspect, but the other is sponsorship.

"What sponsors what to be associated with is a rare commodity - and that means the Champions League."
