GIOVANNI VAN BRONCKHORST never doubted Antonio Colak would hit the ground running this term after seeing the striker become an instant Ibrox hero.
The Croatian took his tally for the campaign to 13 goals for Rangers with another clinical double in the 4-0 victory over St Mirren on Saturday.
It was the third time in as many games that Colak has bagged himself a brace after he also inspired Rangers to wins over Dundee United and Hearts in recent weeks.
