Manchester City have completed the signing of Brazilian defender Vitor Reis from Palmeiras.
The 19-year-old has signed a four-and-a-half-year deal with the Premier League champions, who brought in Uzbekistan defender Abdukodir Khusanov on the same length contract on Monday.
"I'm excited to join Manchester City, one of the biggest clubs in the world," Reis said.
"Everyone has seen the amazing achievements in recent seasons and I want to make my mark as we seek more trophies.
"Working with Pep Guardiola is something every young player wants to do and I know he can help me to develop into the best player I can be.
"City also have a lot of experience of working with Brazilian footballers and joining the likes of Ederson and Savinho in the squad will be a big help to me."
City's director of football Txiki Begiristain added: "Vitor Reis is one of the most promising young defenders in the world and we're delighted to been able to bring him here.
"He is excellent on the ball and outstanding in the air - he has all the attributes needed to be one of the best.
"Vitor is very young, but his quality is so high that we believe he can help us now and for a long time into the future."
Elsewhere, Aston Villa have signed defender Andres Garcia from Spanish Segunda Division side Levante.
Garcia has made the move to Villa Park for an undisclosed fee, with Villa also not revealing the length of the contract.
The 21-year-old full-back came through the ranks at Levante before breaking into the first team and has scored three times this season.
Garcia joins fellow new arrival Donyell Malen in Unai Emery's squad following the Netherlands international forward's move from Borussia Dortmund last week.
