Luis Alberto Díez Ocerín (born 9 July 1992), commonly known as Tato, is a Spanish footballer who plays for Toma Maglie as a midfielder.
Born in Santander, Cantabria, Tato was a product of hometown club Racing de Santander's youth ranks. He made his senior debuts with the reserves in the 2009–10 campaign, aged only 17, in Segunda División B.
Tato made his first-team – and La Liga – debut on 6 March 2011, playing the last two minutes in a 1–3 home defeat against Real Madrid.[1] He spent the vast majority of his spell registered with the B-side, however.
On 26 June 2013, Tato signed with Sestao River Club in Segunda División B.[2] After featuring regularly for the Basques he moved to another reserve team, Sporting de Gijón B in the same level.[3]
On 23 May 2016, Zira FK announced that Tato had left the club after one season in the Azerbaijan Premier League.[4] On 23 September he returned to his home country, signing for UM Escobedo.[5]
