Although no one was willing to speak on record because of instructions from the cricket board but a team official said everyone in the team was angry because of the reports.
"This is getting too much. Every time our team starts doing well or wins a series, these baseless reports come up. There is a lobby that wants to demoralize our players," the official said.
He said the board had told the players to remain focused on their cricket and the T20 match scheduled for today and they would handle the issue.
The report stated that "concerns were raised, in particular, around the tied third match of the series played in St Lucia a week ago on Friday, as well as the final game, which resulted in a last-ball win for Pakistan."
