Isaác Brizuela Muñoz (Spanish pronunciation: [iˈsa(a)k βɾiˈswela]; born 28 August 1990),[3] also known as El Conejo,[4] is a professional footballer who plays as a winger for Liga MX club Guadalajara.

[3] Brizuela was born in the United States to Mexican parents who worked in California at the time.

In January 2013 Brizuela was loaned to Atlas for six months in order to get more playing time.

His successful campaign at Atlas, where he was crucial for the team finishing the 2013 Clausura in third place, entering the quarterfinals and avoiding relegation, prompted Toluca coach José Cardozo to include him in the club's squad once again.

He was included in Miguel Herrera 23-man world cup squad, but didn't appear in any matches.
