Cristiano Ronaldo could be key in Manchester United's interest for Atalanta defender Merih Demiral.

Demiral is on-loan at La Dea from Juventus and is being tracked by United scouts this season.

His impressive form has alerted the attention of Atletico Madrid and Real Madrid, as well as United - who are 'closely following' Demiral's progress. Atalanta reportedly hold a £23.4million option to turn the defender's temporary spell into a permanent one at the end of the season.

While United may not be able to offer Demiral Champions League football in a bid to entice him to Old Trafford, it's hoped that the defender's close bond with Ronaldo could prove to be persuasive. The pair played together for a number of years at Juventus, with Demiral admitting earlier this season that Ronaldo was "one of the best people" he'd ever met as he talked up the Portuguese superstar's impact at Old Trafford.

“There's a strong bond between Cristiano and me. He's always helped me and we often chat on WhatsApp. I think he is one of the best people I've ever met," remarked the Turkey international.
