The 23-year-old -- a member of the Mexico squad that reached the last 16 at the World Cup -- will sign his contract once he has undergone the medical, Atletico said on their website.

"We are so proud, 'the eagle' Raul Jimenez is the new player of Atletico Madrid," rejoiced America, who are known as the 'Eagles', on Twitter.

Jimenez, who has scored four times in 23 international appearances and found the net on 35 occasions in 98 matches for his club, will be Atletico's third forward signing of the close season after they sold their leading scorer Diego Costas to English Premier League giants Chelsea.

French international Antoine Griezmann came from La Liga rivals Real Sociedad while Croatian star Mario Mandzukic joined from German champions Bayern Munich.

"He is an explosive player who will complete our attackinhg line-up for the season," said Atletico's sporting director Jose Luis Perez Caminero.

Atletico get their title defence underway with an away game against Rayo Vallecano on August 25.
