Manchester United boss Sir Alex Ferguson has taken aim at PSG's mega spending.

Fergie can't understand how PSG will qualify for the Champions League when Michel Platini's Financial Fair Play laws are put in place.

"The qualification requirements for the Champions League are not a victory or second place in the league: you can't enter without an invitation," he said.

"But when someone [PSG] pays £36million for a boy of 19 [Brazilian Lucas Moura] you have to say football has become crazy."
