Steven Gerrard feels England have work to do before they can challenge the big sides - but he reckons they "made a statement" against Bulgaria.
Friday's 4-0 win at Wembley flattered Capello's men but there were definitely signs the players who had performed so miserably in South Africa had begun to find their feet again.
Gerrard said: "We've made a statement.
"I've said, after the disappointment of the World Cup, it's going to take time before this team can be really ready to challenge the big sides."
Gerrard believes last night's display saw England "playing the way we should be playing" and he is demanding a repeat in Tuesday night's second Group G game in Switzerland.
"The important thing now is not to get carried away and try to build on that," he said.
"Tuesday's going to be even more difficult. It's a tough game away from home. They're a good team, Switzerland.
"Hopefully, that will breed a bit of confidence."
Tuesday's match is arguably England's toughest of the entire qualifying campaign, with Switzerland the one team they will face who managed to reach this summer's World Cup.
Not only that, but they were the only side in the tournament to beat new world champions Spain, stunning them with a 1-0 victory in their opening game.
Gerrard is in no doubt of the threat England will face in Basle.
"Internationals away from home are always going to be difficult," he said.
"Switzerland showed in the World Cup what a good side they are by beating Spain.
"So we'll have to perform to the same level as we did if we want that result."
