Matthew Upson believes playing without fear is key to England's chances of progressing further in the World Cup.
Following the injury to Ledley King and suspension for Jamie Carragher, Upson was drafted into the heart of defence by Fabio Capello as the Three Lions beat Slovenia 1-0 to make the last 16.
He is now looking forward to helping Capello's side push on in the tournament - but believes they must play with the same freedom as against Slovenia.
Upson said: "I think it was noticeable for everyone the first couple of games (the draws against USA and Algeria) that we weren't flowing the way we can do.
"I thought we showed a lot of good patches of that today and I think that is the freedom that we played with and the change in attitude and the way we kind of just went about our job like it was a Saturday afternoon in the Premier League - I think that is the key for us."
He agreed the tempo had been more like a Premier League game, continuing: "Yes definitely - especially at the end, they started hitting some long balls and it was dropping down, it was a bit scrappy.
"We are more than used to dealing with that kind of football so we did well to see that through."
Among his contribution, Upson had to make a crucial tackle to deny Slovenia a goalscoring opportunity.
He said: "It was just a bit of a reaction really - the ball got flicked on I think and a knockdown so I just turned inside me and just saw the opportunity to take it so it had to be timed right, it was and I was really pleased.
"There's lots of opportunities in a game, lots of decisions to make - every minute of the game there's something you've got to think about and make a decision - so it was a reaction more than anything and I'm pleased I got away with it."
