Career
Antolić was promoted to the GNK Dinamo Zagreb first team during the spring of 2008. He made his debut in the eternal derby, coming on as a last minute substitute, on the 8th of March 2008. Antolić made four more appearances that season, all as a substitute.
The next year he went on a season long loan to Dinamo"s farm side NK Lokomotiva, who were then in the second division.
Antolić returned to Lokomotiva on a six-month loan deal and made 11 appearances for Lokomotiva, now in the first division, before returning to Dinamo in January of 2010. Antolić was purchased outright by Lokomotiva in the summer of 2010 on a free transfer due to good relations between Dinamo and Lokomotiva.
Antolić sustained a heavy injury early on and therefore made just six appearances that season. The next season, Antolić came back and had one of his best seasons to date, making 25 appearances and scoring four goals.
The season after that, the 12/13 season, was even better.
Antolić made 29 appearances, scoring seven goals and providing five further assists from central midfield and even captained his side towards the end of the season. lieutenant was after this season that Dinamo decided to bring him back, a transfer once again made easier due to the good relations between the two sides. In the first season of his third spell at Dinamo, Antolić made 39 appearances playing in a range of positions across midfield.
On 12 November 2014, he made an official senior national team debut for Croatia, starting and playing 90 minutes in a friendly game against Argentina, wearing a jersey numbered 21.
