Martinez averaged more passes per 90 minutes than any other Eredivisie player, while only two players directed more passes forward.
Martinez is able to play through opposition lines but he is also able to switch the play and pick out his teammates over long distances. No player averaged more successful long passes.
He is small for a centre-back and was voted the player of the year by his peers.
He made more headed clearances than any other player and won more aerial battles than any other player, giving him a success rate of 71 percent and putting him second only to Harry Maguire among current centre-backs.
He is helped by a sound reading of the game, which is something he can expect to face more often in the premier league. He is well-known for anticipating strikers' runs and positioning himself to make tackles.
He's all the more attractive to Premier League teams because of his versatile and technical skills.
