Cristiano Ronaldo was key to Sporting CP signing Juventus midfielder Stefano Sturaro last month.

Sturaro is on-loan at Sporting this season, with Ronaldo the key man in the deal.

Speaking to A Bola, his agent Carlo Volpi revealed: "Ronaldo told him that Sporting is a very prestigious club, always fighting for the title, it would have been a good solution for him, a very prestigious club and a beautiful city guaranteed him by Ronaldo.

"It was the fans who conquered Stefano, he was in Lisbon two times and he saw two games, he told me that the fans are shaking the stadium, just the way he likes it."
