Collingwood has been delighted with England's progress
England captain Paul Collingwood urged his side not to get carried away after they eased into a Thursday semi-final at the World Twenty20 in the Caribbean.
A three-wicket win over New Zealand made it four wins on the bounce, and Collingwood told BBC Sport: "It was another fine all-round display.
"You could see from the performance we wanted to keep the momentum going and that winning habit, which is important.
"But I want us to keep our feet on the ground - we haven't won anything yet."
Pakistan's win over South Africa earlier on Monday ensured England's place in the last four was guaranteed before a ball was bowled in their match against the Black Caps.
Collingwood's side refused to sit back and take the match in St Lucia lightly, restricting New Zealand to 149-6 and then chasing down the total in a professional manner with five balls to spare.
"It was great to see the guys come out and play play with the same intensity and spirit as last few games," Collingwood told Test Match Special. "It would've been easy for us, having found out we were through, to go out and take it easy.
"But you can see from the performance we wanted to keep the momentum going and that winning habit, which I think is important.
"I thought we adjusted well to the wicket. We employed plenty of pace variations and we kept them down to a score that was probably 10-15 runs less than they wanted.
"After that, special mention has to go to the guys at the top of the batting order. When you're chasing a target like that it sometimes isn't easy when the ball gets softer, so to go out there at the top and take the game right to them is a joy to see and it really helps the middle order."
Having topped their group, it would appear likely that England will avoid a clash against Australia in the semi-finals, but Collingwood insisted: "All the teams in the semis will be strong teams - no matter who we get we'll have to adjust to the wicket and keep playing good cricket."
They should be able to do so, though, with the help of Kevin Pietersen, who missed this match to attend the birth of his baby son but who should be back in the West Indies in time for Thursday's semi-final.
"I think KP will be back in the next couple of days," said Collingwood. "The timing seems pretty good and everyone's healthy, which is the main thing, so hopefully he'll be back and raring to go for the semis.
"The way he's been batting is fantastic to the team, he's brought real power to the side, and of course it'll be fantastic to have him back.
"We're progressing and improving all the time, thinking for ourselves out on the field, and it's exciting because we have a lot of power in the side and the bowlers really are adjusting to the wickets which is crucial."
Man of the match Tim Bresnan, meanwhile, insisted England need not fear anyone as they target what would be a first major ICC trophy.
Any team with momentum has a very good chance and they've won three very good games now so they'll be a very tough team to play in the semis
Vettori on England
"You can gather a lot of momentum in this form of the game, and it was good that we did that with victory again today," he said. "We were ruthless today and hopefully that bodes well.
"Whichever team we get (in the semis)... we have momentum and are playing well, so bring them on."
New Zealand skipper Daniel Vettori blamed his side's batting for their defeat and subsequent exit from the tournament.
"We could have bowled better, we needed to take wickets in clumps and we probably took them a little too late, but in all forms of the game batting has probably been our problem - not putting enough runs on the board," he said.
"Our 150 was a competitive total but maybe 20 below par and we couldn't put pressure on them.
"We have some talented batsmen but there were not enough runs today."
Asked about his thoughts on England's prospects in the knockout stage, Vettori said: "Any team with momentum has a very good chance and they've won three very good games now so they'll be a very tough team to play in the semis."
