Charles Mariano Aránguiz Sandoval (Spanish pronunciation: [ˈtʃaɾles aˈɾaŋɡis]; born 17 April 1989) is a Chilean professional footballer who plays as a midfielder for Universidad de Chile.

With his former club Universidad de Chile, Aránguiz was considered one of the best midfielders in the Chilean Primera División, with a good sense of tactics, impressive stamina and intelligent playmaking, marking and passing abilities.

He is described by FIFA's official website as "a crafty, tigerish midfielder of the highest order, notable for his ability to win and distribute the ball, pick out passes and hit the back of the net".

[3] In 2010, Aránguiz had a short spell at Argentine club Quilmes, before joining Colo-Colo's historic rivals Universidad de Chile for a fee of £616,000 on 1 January 2011.

[7] Having drawn 3–3 on aggregate with Unión Española in the semi-finals of the Copa Chile, Aránguiz led his team to the final, netting the "U"'s first kick in a 5–4 penalty shoot-out victory on 17 April 2013.

[9] On 11 January 2014, it was announced that Aránguiz was signed by Brazilian club Internacional on loan until 15 August 2014 from Granada, after its owner Giampaolo Pozzo, who also owns Udinese and Watford, had bought half of his rights from Universidad de Chile.

He established himself in the Chile team during its successful 2014 FIFA World Cup qualification campaign, making seven appearances and scoring in wins against Bolivia and Venezuela.

[23] At the 2015 Copa América, held in Chile, Aránguiz scored twice during a 5–0 defeat of Bolivia which ensured that La Roja would progress to the knockout stage as Group A winners.
