Example Input: Question: Where do the Premier League team that signed Rodriguez to a four-year contract play their home games? Passage:On 28 August 2015, Rodríguez signed a four-year contract with Everton of the Premier League for a reported fee of £500,000. Manager Roberto Martínez said that he would likely be put into the first team due to his experience in top-flight football in his homeland. However, Rodríguez made his debut for the under-21 team on 7 September. In his debut, he would head in Ryan Ledson's cross to open a 3–0 home win over Preston North End in the Lancashire Senior Cup. Fifteen days later, he was included in the senior squad for the first time, but remained on the bench as an unused substitute in a 2–1 win away to Reading in the second round of the League Cup. Rodríguez made his Everton first team debut on 9 January 2016 in the third round of the FA Cup when he replaced Aaron Lennon for the final minute of a 2–0 win over Dagenham & Redbridge at Goodison Park.

He appeared in the 2018 biographical drama film Vice, opposite Amy Adams, Steve Carell, Christian Bale and Sam Rockwell. The film explores the life of politician Dick Cheney and is directed by Academy Award-winner Adam McKay. Sklenar will appear in Amir Naderi's upcoming film Magic Lantern, in addition to films The Last Room and Glass Jaw.
