Skipper David Beckham is confident England will improve after two laboured performances in their opening group matches.
Beckham said he was always confident England would beat Trinidad & Tobago despite leaving it very late to break the deadlock.
“We never give up. That’s the message we give out – that’s the message we always give out,” said the midfielder.
“You’ve not seen the best of us yet. We know we can play better and there’s better to come.
“We knew it wasn’t going to be easy today, people expected it to be easy but we knew if we kept at our game plan we would break them down,” added Beckham.
“The good thing about the game is that we finished strongly.”
Beckham was pleased to see the introduction of Wayne Rooney as a second-half substitute, alongside Aaron Lennon.
“He is ready now. He needs to get on and get fit and the manager made some good substitutions – very positive – and we pushed forward from that,” said Beckham.
Eriksson said he was happy with the performance.
“I am rather pleased, the players showed a lot of patience and that paid off,” said the Swede.
He offered his support to striker Michael Owen, who was replaced by Rooney after 58 minutes, having also being substitued against Paraguay.
“I think he gets better and better. He is another player who hasn’t played football for a long time,” said Eriksson of Owen.
“We must now immediately begin our preparations for the game against Sweden. We haven’t beaten them for a long time, so it would be nice to do it in Cologne.”
