Karachi, May 17 (IANS): Unhappy with the performance of 'some' senior players, Pakistan's Twenty20 captain Shahid Afridi has requested the national selectors to inject some young blood in the team.

In an interview prior to the team's departure for London from St. Lucia, the Pakistan captain expressed his dissatisfaction at the performance of some of his senior players during the recently-concluded World Twenty20.

"It is time for some senior players to go because we can't expect a good show from them anymore in future," said Afridi.

Afridi feels that by grooming youngsters the team can get better results in the future.

"There is no dearth of talent in Pakistan especially in the T20 format; the youngsters should be given a chance in the national team."

Defending champions Pakistan lost to Australia in a thrilling semi-final and Afridi still can't believe that Pakistan lost the game.

"I haven't seen such an unbelievable game in my career, the entire match changed in just 11 deliveries, the battle would long be remembered," said.

Michael Hussey's magical knock of 60 off 24 balls enabled Australia chase down a huge target of 192 to win the semi-final last Friday.

Counting the positives of the Caribbean safari, Afridi said unity among the players was the best he earned during the tournament.

"Every player was united and everyone was fighting for victory, which is a great sign for team," he said.
