The AC Milan forward now says he does not deserve to be honoured with the medal because he did not play in Russian Federation.
Speaking to reporters, Kalinic acknowledged that he played no part of Croatia's historic World Cup run and therefore refused the chance of owning a World Cup finalists medal.

The Milan striker refused to come on as a substitute in Croatia's 2-0 win over Nigeria, citing fitness issues, but was then kicked out of the squad by head coach Zlatko Dalic.

The Blazers boss Dalic was bitter with the attitude put out by the former Blackburn player, having encountered a similar incident with Kalinic against Brazil in a pre-World Cup game.
In the absence of the 30-year-old forward, Croatia were left with just one designated striker, Mario Mandzukic, who rose to the occasion, scoring three goals in six appearances, including one goal in the final as well.
