"They weren't allowed on tour until after the series had been won.
"Your mind needs to be completely focused on it. Cricket is a sport that requires complete concentration.
"You need everything going for you and I'm not sure they're pushing for that hard enough."

He added: "I don't think they are playing like a cohesive unit that love each other.
"I don't think there was enough heart in that performance, there definitely wasn't enough technique, there definitely wasn't enough grit to stick it out.
"There will be an investigation into this for sure, Cricket Australia have really got to investigate what's in that dressing room.
