England hope champagne flows after the South Africa series
England captain Michael Vaughan says his side will face sterner tests later this summer after securing a 2-0 series victory against New Zealand.
After a one-day series against the Kiwis Vaughan's team face South Africa and the skipper said: "That will be the ultimate test of where we are at.
"I never envisaged winning against the Kiwis by an innings but full credit to the way we've played our cricket.
"The catching was very good but we also know there are areas to improve."
It was James Anderson who inspired England's innings victory over New Zealand at Trent Bridge, a win that lifted them one point above the South Africans to third in the Test rankings, one below second placed India.
A modest Anderson praised the efforts of fellow seamer Ryan Sidebottom after he was named man of the match in England's comprehensive win.
The Lancastrian was rewarded for his match figures of 9-98 at Trent Bridge, but he said he was due a performance worthy of his new-ball partner.
Sometimes I don't think he knows how good he can be

"Ryan has had a great 18 months and it was about time someone helped him out, luckily enough it was me," he said.
"The ball swung right away, it was great conditions for all three of us."
Ironically one of England's seamers may not have played if Andrew Flintoff had been fit to return to the side.
Vaughan is hopeful, however, that his influential all-rounder will recover from a side strain in time for the South Africa Test series, which begins at Lord's on 10 July.
"Everyone knows that, if he is fit, I would love to have him in the team," Vaughan enthused.
Regarding the make up of his bowling attack he added: "You would love five, but I am also happy with four, it can work, and the balance of the team has to be very important when you play a good team like South Africa.
"It will probably be Freddie who will have to make the call: if he is confident enough in his own form and his body whether he plays."
Anderson ended the three-match Test series as the leading wicket-taker with 19 dismissals, including brilliant figures of 7-43 in New Zealand's first innings in Nottingham.
The 25-year-old produced two unplayable deliveries at pace to bowl opener Aaron Redmond and big-hitting Brendon McCullum, sending both batsmen's off stump cartwheeling out of the ground.
He has formed an effective trio with Sidebottom and Stuart Broad, but Anderson remained modest when asked about his superb bowling performance on Friday.
"I just managed to get the ball in the right areas and they missed it, which was nice," he said.
He burst on to the international scene during the 2003 World Cup in South Africa, but has since endured an inconsistent five years, suffering from lack of confidence and form.
Although the fast bowler admitted it was "fair" he had been mercurial in the past, Anderson said he is looking to rectify that long-term.
"It's something I'm looking to improve and hopefully I'm going in the right direction," he added.
Anderson's recent development has been closely monitored by England bowling coach Ottis Gibson, who said the "Burnley Express" has the ability to become a world-class fast bowler - if he can only improve his self-belief.
"I have been working with him day in, day out and I know what he is capable of," the former West Indies all-rounder told BBC Radio 5 Live's Sportsweek.
"It's just a case of getting him to believe it as well.
"Sometimes I don't think he knows how good he can be. He'll have a bad spell and that can affect him for the whole day.
"But if you have a bad day you're not a bad bowler - it's a case of getting him to believe that."
Vettori's own form with the bat summed up New Zealand's demise
Meanwhile, New Zealand skipper Daniel Vettori admitted his side had much to address after their second series defeat to England in the last six months.
"We have not been able to keep up with the pace of England," he conceded. "It's a lack of ability on our part and a lack of fortitude as well.
"I don't want to take anything away from England. They have dominated us since Old Trafford on the third day. We have to appreciate how well they played and how well their swing bowlers swung the ball.
"When you get guys like James Anderson bowling the way he did there is very little you can do.
"It sums up the state of affairs that we are in, we are able to compete for a period of time but not for a whole five days."
