The London club wants to consolidate its line of attack in the winter transfer window, and finds in Mariano the right solution.
According to the newspaper, Mariano was not the first choice for coach David Moyes, but rather he was considering signing Luca Jovic from Real Madrid.
But because Marianos transfer value would be lower, he could cost West Ham 20 million pounds, and by the end of his contract in 2023, the 27-year-old became the favorite of the English club.
Mariano has played for Real Madrid since 2012, when he represented the Under-19 team.
Mariano moved to Leon in 2017 before returning to Real Madrid in 2018.
Mariano played 47 matches for Real Madrid’s first team, scoring 11 goals.
