ATK head coach Antonio Habas criticised the referee following his team's 1-2 defeat against FC Goa on Saturday at the Fatorda Stadium.
Jobby Justin's 64th-minute goal had ATK level with Goa but the Kolkata-based club conceded to Ferran Corominas again two minutes later before ultimately ending the game without any points.
After the game, Habas said, "It was not a good match for us. The referee did not allow anything for us. It is impossible when there is refereeing is like this.
