Bruno Fernandes is comparable to Frank Lampard and "on another level" to Atletico Madrid sensation Joao Felix.
That's according to former Sporting Lisbon boss Carlos Carvalhal, who has heaped praise on Manchester United's new January signing.
Fernandes has put pen to paper on a five-and-a-half year deal with the Old Trafford club, and could make his debut this weekend.
Manchester United have lacked creativity in the middle of the park this season, and boss Ole Gunnar Solskjaer is hoping Fernandes can assist in this area.
Carvalhal never managed Fernandes at Sporting, but the current Rio Ave boss has some strong opinions on the type of player he is.
"He is really very good," Carvalhal told talkSPORT.
"He is a player from another planet, the planet of Portugal is very small to him in this moment, he's an extraordinary player.
"Bruno is the best player in the league, he's miles ahead of the others.
"He is a complete player, and if you ask me to compare Bruno with a player, I will say Frank Lampard."
Carvalhal added: "About money, I don't know too much, but when Benfica sold Joao Felix to Atletico Madrid for €126m, the fans of Sporting will look to that and think: 'Come on, €65m [for Fernandes] is not enough!'
"Bruno Fernandes is another level to Joao Felix in my opinion, but I don't know if Bruno at 19 years old was the same level as Felix is now.
"But he is a ready player, he's a complete player."
