Juan Mata has backed his Spain teammate Diego Costa to succeed in the Premier League ahead of his proposed move to Chelsea.
Mata will link up with the Brazilian-born Costa for the World Cup after the Atletico Madrid striker opted to represent Spain instead of his native country.
Although having played very little football with him so far, Mata believes he has seen enough to know that Chelsea are about to make a very good purchase. The Manchester United playmaker, who left Chelsea in January, says Costa has the physical attributes to succeed in the English game.
He said to reporters: "I don't know if it's been confirmed yet - I don't think so.
"I wish him the best. He's a forward who is very well suited to English football because of his power and strength.
"He's the type of player that thrives there."
Mata was speaking ahead of the imminent completion of Costa's £32m deal that will take him to Stamford Bridge. Jose Mourinho has been chasing the player for some time with some reports claiming Costa agreed personal terms with the Blues as long as two months ago.
The arrival of Costa will be a major step towards Mourinho forming the Chelsea team he wants. Another major part of that plan involved selling Mata to Manchester United in a £37m deal in January.
Costa may not be the only Spanish international to arrive this month as it is looking increasingly likely that Cesc Fabregas will also sign in a £27m deal from Barcelona.
