Pakistan are currently locking horns with England in a seven-match T20I series. The visitors are leading 2-1 after three games.
Ramiz Raja has warned the players ahead of the ICC T20 World Cup in Australia.
The Men in Green will head on with India on October 23 at the Melbourne Cricket Ground.
Pakistan defeated India for the first time in the last edition of the global event. The batting line-up is dependent on Babar Azam and Mohammad Rizwan.
All the players have been informed by the national cricket board that losing is not an option in Australia.
“I told them we need to win because fans want us to lift the trophy. If they lose, I can’t take it as I am a bad loser,” Raza was quoted as saying by Geo TV.
“I feel like hitting people around me when I see Pakistan losing. I am a terrible watcher and gets scolded at home for offending others while watching a game,” he added.
