It was expected to be the biggest grudge match in the Cricket World Cup, and that animosity was on display among rival fans at the Merrylands RSL Club watching the showdown between India at Pakistan on Sunday night.

Four people were taken to hospital with a range of injuries after a wild brawl broke out between about 40 fans watching the match on a big screen at the club on Military Road about 9.30pm.

A NSW Police spokesman said a group of fans had gathered to watch the match, broadcast live from the Adelaide Oval, when tensions boiled over.

Chairs and tables were hurled across the room, and police confirmed one person was hit on the head by a glass that was thrown.
