Melbourne City goalkeeper is left bloodied after being smashed in the face with a BIN as A-League game descends into chaos with fans invading the pitch to protest controversial $10MILLION NSW deal

The Melbourne Derby descended into chaos on Saturday night as fans invaded the pitch and attacked City's goalkeeper at AAMI Park.

Furious with the A-League's decision to send the next three grand finals to Sydney, fans were planning to stage a mass walkout on the 20th minute to vent their discontent with the decision.

However, tempers boiled over and by the 21st minute, supporters encroached the pitch and City goalkeeper Thomas Glover was attacked, with a bin smashed into his face.

City confirmed that Glover has likely suffered a concussion and was receiving treatment in the dressing room.

Since the A-League started in 2005, clubs have needed to earn the right to host the grand final based on how they performed in the finals series.
