Brazil winger Savinho has joined Manchester City on a five-year contract, the English Premier League champions said on Thursday.

The 20-year-old was on loan from French club Troyes at Spanish club Girona last season, scoring nine goals in 37 La Liga appearances.

"I’m so happy to join Manchester City... Everyone knows they are the best team in the world right now," Savinho said in a statement.

Manchester United have signed 18-year-old French defender Leny Yoro from Lille on a five-year contract, as they bid to shore up their defence.

Sources say United agreed to a $67.56 million fee for Yoro, who has played 60 games for Lille. The centre-back, who made 41 appearances last term, was named in the Ligue 1 team of the season after helping Lille finish fourth and secure a Champions League qualifying spot.

United forward Mason Greenwood has joined Olympique de Marseille on a five-year deal, the clubs said. British media reported that the 22-year-old United academy product will cost the Ligue 1 club up to 31.6 million euros.

Greenwood made 129 appearances and scored 35 goals for United.
