Jose Mourinho has called upon Manchester United to spend money on transfers if they want to rejoin the elite clubs of Europe.
United lost to Juventus 1-0 in the Champions League on Tuesday.
Mourinho spent £68 million to sign three players but was unable to bring in another center back.
"To go to the Juventus level? Barcelona level? Real Madrid level? How can you reach that level? Manchester City level? How can you reach this level?" he pondered.
"Juventus is champions for seven years, I think seven years in a row," Mourinho told a news conference. "Two Champions League finals in the last four or five years and not happy with what they have.
"They want more, they want more. They had [Gonzalo] Higuain, [Mario] Mandzukic, [Paulo] Dybala, they want more. They want Ronaldo. They had [Andrea] Barzagli, [Giorgio] Chiellini, [Danieli] Rugani, they are not happy, they want more. They want Bonucci and they go for the best players in the world.
"So a big, big club with a big past, but with also a big desire to have a big future and everything they put there to try to win, I don't say the Champions League, I think to win the treble. That's what they want because normally they win at home."
