England give Joe Denly a chance to be new Kevin Pietersen

Little more than 24 hours after confirming that Jonathan Trott will face Australia at the Brit Oval in this week's deciding Ashes Test, the selectors have identified Kent opener Denly as the player to fill Kevin Pietersen's shoes - or at least try to - when it comes to one-day cricket.

With Pietersen out of the equation until this winter's tour of South Africa after recently suffering a setback in his recovery from Achilles tendon surgery, England believe the time is right for the uncapped 23-year-old Denly to step forward for the first time.

The dashing young batsman will go to Belfast next week for a one-day international against Ireland and he also features in the squad for two Twenty20 internationals against Australa.

But the big prize for Denly is to be part of the squad that will tackle the Aussies in a seven-match NatWest Series next month and then go straight on to South Africa for the Champions Trophy.

"Joe has impressed us with some excellent performances in one-day cricket and, with Kevin Pietersen unavailable, this is an excellent opportunity for him to step up to the next level and show what he is capable of," said national selector Geoff Miller.

Denly averaged above 50 in this season's Friends Provident Trophy competition and has formed an exciting opening partnership with Rob Key at Kent. Once again, though, there is no place for Key in England's plans.

Talked about as a candidate for this week's Test but ignored, the county captain has even fallen out of the Twenty20 squad - despite being a member of England's party for the World Twenty20 a couple of months ago.

Although Andrew Flintoff's name appears in all of today's squads, his involvement in any of the limited-over matches between now and October hinge on how his fragile right knee stands up to this week's Ashes battle.

There has been talk that Flintoff - who is retiring from Test cricket after The Oval showdown - may need more surgery, having gone under the knife only four months ago.

Ian Bell, who will bat at No 3 for England this week, has lost his place in the 50-over side, as has Dimitri Mascarenhas. And, as for the two Twenty20 internationals against Australia at Old Trafford if a fortnight or so, James Foster, Graham Napier and Mascarenhas join Key on the discard pile in the wake of England World Twenty20 failure.

Matt Prior, Trott, Tim Bresnan and Flintoff - who was unavailable in June because of injury - make a squad captained by Paul Collingwood.

Possibly the biggest surprise, though, is that only Andrew Strauss will be rested for next week's match in Belfast, which takes place just three days after the end of the Ashes series.

Collingwood takes the reins for that game and players such as Flintoff, Jimmy Anderson and Stuart Broad are all listed to travel, despite their Test exertions against Australia.
