​Portugal and ​Juventus superstar, ​Cristiano Ronaldo has opened up on fellow countryman, Bruno Fernandes, revealing that he cannot understand why none of the top European clubs haven't yet signed him in the summer.

Fernandes who played a key role in Sporting Lisbon's title-winning last season has been linked with Manchester United who are yet to table an offer for the midfielder despite desperately needing reinforcements in midfield following the departures of Ander Herrera and Marouane Fellaini.

As per the ​Mirror, United manager,​ Ole Gunnar Solskjaer has reservations over Fernandes' passing ability and while Real Madrid are understood to be considering a late move for him, it is likely that he will remain in Portugal for another season.

Fernandes who starred for Portugal along with Ronaldo on their way to winning the UEFA Nations League, came for praise from the 34-year-old who is bemused that he has not left for a bigger club.

"In the national team you have Cancelo, Bruno Fernandes, who nobody knows why he doesn’t leave. In the national team, you have a lot of talent, so I see the light at the end of the tunnel. Possibly this new generation will be the best at the talent level, but that’s not enough," Ronaldo said to TVI1

"They have to want to. I have spoken to him. Positive, I’m a captain who wants to help and be helped. ‘The atmosphere in the national team is spectacular. The last few years have been the most enjoyable, both because they want to learn and because there is this."

Widely considered to be one of the best young footballers in the world, Fernandes has been Sporting's best player over the past two years, scoring 47 goals in 106 appearances for them so far.
