Greenwood - room for improvement (Getty Images).

Will Greenwood has hailed France as the RBS Six Nations' form team but is still backing England to do the business in Paris.

The old rivals meet in the final match of the championship at the Stade de France on Saturday evening in a repeat of the World Cup semi-final - and there is plenty at stake for both sides.

Les Bleus are just one victory away from claiming a Grand Slam, their second in three years, while England must win by seven points if they are to retain their Six Nations crown.

The bookies make Bernard Laporte's men favourites following the ease with which they have closed on a championship clean sweep, but Greenwood believes England can rip-up the form book.

"France are not a side full of superstars. They trust each other and you can see that in the way they play," said the Harlequins centre and England vice-captain.

"If they miss a tackle then they know three or four of their friends will cover for them, and that's a great situation to be in.

"Most people will say they are playing the best rugby in the tournament and are deserved table toppers. But as a core group we've been to tough places and still come away with results.

"We know what to do and we've done it in the past. There is no fear about the weekend, just plenty of excitement. It's a great opportunity."

England's lack of progress since the World Cup triumph has been the source of some concern with the chief suspicion being they are still suffering a hangover from their heroics in Australia.

They disposed of Italy and Scotland easily without ever hitting top gear, only to then see their Grand Slam dream derailed by Ireland who shattered their proud unbeaten record at Twickenham.

Wales looked capable of following suit last Saturday before running out of gas as England used the last 15 minutes to rediscover the form which swept them to glory Down Under.

In that closing period they crushed Welsh resistance with a simple game plan based on driving up the middle and applying pressure - an aspect of England's play which Greenwood feels has been lacking in recent outings.

"It's periods of sustained pressure which allow you to go for the killer thrust in games, but it just hasn't been happening for us," he said.

"A lot of the good stuff comes after sustained pressure. Ben Cohen showed me a video of England against Scotland in 2001 when we doing some analysis.

"In that game it was 8-3 after 35 minutes but England ended up winning 43-3 because we continued to dominate and then the points came. The pressure we are exerting at the moment isn't relentless. France are being relentless.

"France are just playing simple, direct rugby and applying pressure and squeezing the life out of sides. They're taking their opportunities - to win 31-0 in Scotland is a fantastic result.

"But when you watch that match it doesn't seem like they stuffed the Scots. It was just suddenly 31-0.

"It's frustrating because that's what we were good at. We used to restart, get the ball back, boot it 70 yards, put pressure back on their line-out and then we'd be back in.

"Now we're knocking things on and getting turned over in the wrong areas of the field. It's allowed the opposition relief from the pressure-cooker environment.

"The fantastic, fluid, rhythmic play that people are suggesting is lacking at the moment often comes about as a result of a applying territory, domination and pressure. We're lacking those elements and we need to find them again."
