Manchester United legend Rio Ferdinand believes there are huge expectations around new signing Amad Diallo.

The 18-year-old right winger has arrived from Atalanta in a deal that was brokered in the summer.

Diallo secured his paperwork and completed the big money move, which could rise to £37 million if all clauses are met in the coming years.

"We just bought a kid in from Atalanta and hopefully he does something [to boost United's season]," Ferdinand told the FIVE YouTube channel .

"If you see his clips and speak to some of the people at the club that were involved in buying him, potentially this kid could be an absolute world beater.

"I think that's the thoughts of Manchester United people that they've unearthed…. I'm not going to give him that pressure of Cristiano Ronaldo but nobody knew about Ronaldo when we bought him really other than people in Portugal.

"This kid seems quite similar in that sense. if you see his clips and the way people talk about him then I think the world is his oyster if he applies himself right."
