The former fast bowler, commenting in a television channel as a expert, said he was appalled at the way Afridi (0) got out today against South Africa in the fifth ODI.
"He got out two balls before the power play was to start. He knew there was a fielder in the deep and he knew (Ryan) McLaren would bowl a short one, and with 15 overs remaining he still played the shot and got out. I just don't understand this and don't know what to say," Waqar said.
Afridi had twice walked out of team meetings on that tour after differences cropped up between him and Waqar over team selection. After that incident, the team management had described Afridi as a disruptive force in the team.
"Look he is in his mid thirties and his eye and reflexes are not what they used to be. We saw that today. He needed to bat sensibly and with 15 overs remaining he needed to bat sensibly but he didn't and let the team down," Waqar said.
Interestingly, another former Pakistan captain, Moin Khan has also said that Afridi apparently has some fitness issues, which is badly affecting his bowling form.
