Rangers defender Madjid Bougherra says England appeared disunited for their 0-0 draw on Friday.
Bougherra still believes they will qualify for the knockout phase by beating Slovenia in Port Elizabeth next Wednesday.
But the 27-year-old accepts a drastic improvement is required.
"England did not play like a team," said the Rangers defender. "They have good players but for me they were very low.
"But I still think they can qualify for the second round. Then you can see the best of them."
Bougherra must have been surprised at how little he was extended in the heart of Algeria's rearguard.
After losing their opening game to Slovenia, the north Africans were supposed to be the whipping boys for a rampant England to stamp their authority on the World Cup.
But someone got the script badly wrong.
Bougherra did not put the huge fault lines down to fear or pressure, as Capello suggested.
But he did hint at an element of complacency in English ranks, suggesting Algeria had not been given the respect they were due.
"I don't think many people thought England would draw with us," he said. "People thought Algeria were nothing.
"It was just minimal respect, although I could understand it.
"England have so many big stars and not many people know anything about Algeria. But if we are in the last 32 it is because we are a good team and we showed the world what we can do.
"When we played Slovenia in the first game we were afraid. Now all the people are on the street celebrating. They will give us the spirit to go forward."
