Middlesbrough have completed the signing of Aston Villa winger Adama Traore for an undisclosed fee.

Aston Villa announced the move via Twitter on Wednesday afternoon and the Middlesbrough website stated he would sign a four-year deal.

The 20-year-old will make an instant return to the Premier League after a difficult season with the Midlands club last season.

Middlesbrough manager Aitor Karanka said on the club’s official website: “He is another important player and I am expecting a lot from him.

“I’ve known him since he was a kid. He went into the national team just after I left, but I know all about him and what he can do.

“His level is higher than he showed last season, but in the right environment I’m hoping that he will show what he is capable of.”

Traore arrived at Villa Park from Barcelona for £7million last summer but failed to make a name for himself in the Premier League, making just 12 appearances for his side in all competitions.

The Sun had previously reported that Traore has cost a staggering £2.34million per hour of football since arriving at Villa from the Nou Camp last summer.

Middlesbrough have been busy this summer, as former Real Madrid assistant manager Karanka looks to keep the Teeside club in the Premier League.

Karanka has confirmed 10 new signings, with the latest being Arsenal defender Calum Chambers. He signs on loan, as does former Manchester City hitman Alvaro Negredo.

Goalkeepers Brad Guzan and Victor Valdes joined on free transfers, along with Bernardo Espinosa and Gaston Ramirez. Martin de Roon has signed from Atalanta for around £12.75m, while Karanka has also signed Viktor Fischer, Fabio and Antonio Barragan for a combined £7.5million.

In other Aston Villa transfer news, this midfield target could be moving the opposite way from Middlesbrough to Aston Villa.
