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 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.

It 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.
