“We realise that our last game (against Algeria) was totally unacceptable,” Terry told a press conference.
“The manager said after the game that we played without any passion at all. I think first and foremost you need to have that (passion) and I don’t think any player had that the other night.
“I’m sure on Wednesday (against Slovenia) everyone will have the fire in their belly.”
Terry, 29, went on to say he thinks former Chelsea team-mate Joe Cole, along with Wayne Rooney, is the key to unlocking stubborn back lines.
“If he’s called upon, Joe would do a great job,” continued Terry.
“With Chelsea he was a great boost for us coming back from his injury. Joe is one of those players who gives everything and always makes himself available.
“I personally think that him and Wayne (Rooney) are the only two in the side who can really open things up and be the key to breaking down defences.”
The Chelsea captain went on to defend Fabio Capello’s tactical decisions, but hinted that the team would not be afraid of confronting the Italian manager if they feel there are problems.
“We shouldn’t be criticising the manager,” he said.
“It takes a lot of responsibility to be the England manager. We’re here, we’re fully behind him and we know we’ve got his support as well,” he said.
“If we feel there is a problem, there’s no point keeping it in. Whether we have an argument with the manager or us expressing our opinions upsets him, everyone needs to get off their chest exactly how they are feeling.”
Looking ahead to England’s final Group C game against Slovenia, Terry insisted that the players would give their all, knowing that only a win will guarantee qualification to the last 16.
“(Not qualifying) would be unacceptable,” he said.
“I’d be the first one out of the dressing room holding my hands up, but until that minute comes I’m going to keep myself and the lads upbeat.
“It’s not acceptable the way we played, but we’re still upbeat and we go into our last game looking to top the group and that’s the main thing keeping us going at the moment.
“We just need to go out there and think ‘sod it’. We’ve got one more game that will make or break our tournament.
“It’s been three or four weeks away from my family, but I’ve come here to win this tournamentÃ¢â‚¬â€I don’t want to go home on Wednesday.”
