Alastair Cook's captaincy was 'way behind the game' on day two of the third Test and cost England valuable runs, says David Lloyd.
The tourists bowled Australia out for 385 at the WACA but Lloyd told the Sky Sports Ashes Podcast that total could have been 30-40 runs less had Cook deployed a stronger slip cordon.
"England got the early wicket of Mitchell Johnson with a full length ball from Stuart Broad and it seemed to be that Australia would be dismissed for 350," said Lloyd after the close of play, which came with England on 180-4 - some 205 runs behind.
"But all the talk in our commentary box was that Alastair Cook's captaincy was way behind the game.
"There's evidence here that you need a good slip cordon - not just two slips, you need to have four slips for nine, 10 and 11 of any team.
"If you pitch the ball up against them, particularly at this ground, they are not good enough to work the ball to square leg so you can pitch the ball up.
"From what I've seen in this game from the ball going down to third man, is that fourth slip is a massive player. We repeatedly didn't have a fielder in there and Australia got away and got way beyond 350.
He added: "We've got strong opinions in the commentary box and we're all great captains from that position. I understand that we're up here and the guy's out there on his own, but we have to comment and I have never been as animated as that.
"I was thinking 'this is wrong; for goodness sake, someone say 'we've got to have a fielder in that position - fourth slip' where the ball was going repeatedly."
Former England skipper Nasser Hussain agreed with Lloyd but also pointed the finger of blame at senior bowlers James Anderson and Stuart Broad.
"I thought Cook had a poor morning - probably one of his poorest, actually, as captain. Here at the WACA you are going to get a lot of catches in the cordon and you have to hold your nerve because you are going to go for boundaries in other areas, but you are going for boundaries to third man anyway and you could take a catch there.
"They would have comfortably had Ryan Harris, Nathan Lyon and Peter Siddle all caught in that fourth-fifth slip area so it was poor captaincy.
"It was also poor from the bowlers. With 155 Tests between them Anderson and Broad could say 'skipper, I want an extra slip fielder in there'.
"I didn't think Cook had a good morning but neither did Clarke. Cook went out there and nicked one through where fourth slip would have been. Both captains could have done things differently."
