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 can play as a defensive, centre or even as a right wing midfielder. 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".
Aránguiz was born in Puente Alto in Diego Portales neighborhood. His mother, Mariana Sandoval, is a football coach. He started to play football in Universidad de Chile before leaving the club to join Cobreloa Academy when he was 13 years old.

By defeating Ecuadorian side Liga de Quito 4–0 on aggregate in the final, Universidad became the first Chilean side to win a continental competition in twenty years.
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. In the final, he played the full ninety minutes as Universidad secured a 2–1 win over Universidad Católica thanks to a stoppage-time goal from Juan Ignacio Duma.
On 11 January 2014, it was announced that Aránguiz was signed by Brazilian club Internacional on loan until 15 August 2014 from Granada CF, after its owner Giampaolo Pozzo, who also owns Udinese and Watford, had bought half of his rights from Universidad de Chile.
