Pressure mounting on the England captain
In returning to the tried and tested format of six batsmen and four bowlers, England are hoping to give the impression of bolstering their batting line-up.
Tim Ambrose batting at number six at Headingley simply did not look right - he does not yet have a presence at the crease - and although they could have restored Andrew Flintoff to that position, they hope that four bowlers will be enough here.
That could change at The Oval, in the middle of a crucial fortnight for England, especially so for their captain Michael Vaughan, on whom the pressure to score runs is steadily mounting.
He seems relaxed enough in public, but he knows that no captain is fireproof, especially when his team is losing.
Add loss of form to that and the situation can quickly become serious and, having scored only two hundreds and four fifties in his last 29 Test innings, Vaughan's predicament is starting to have a worryingly permanent look to it.
He is fortunate that there are no obvious rivals at present - Andrew Strauss is feeling his way back, Paul Collingwood is also short of runs and the only real contender, Kevin Pietersen, needs to be left alone to concentrate on playing big innings.
There might be some raised eyebrows at Stuart Broad's omission from the final XI, particularly after his lovely batting at Headingley. But his bowling looked tired and rather lacklustre there after the marathon stint in the field at Lord's, and England are understandably nervous about playing him here as one of only four bowlers.
I suspect the same concern was raised about Steve Harmison, and with Andrew Flintoff now able to add some aggression and Ryan Sidebottom a different angle, this is the best balance for now.
But England will probably need to turn to five bowlers again in the near future, and so will face the same conundrum as at Headingley. This is what puts Ambrose's neck on the line here as England continue their five-year search for Alec Stewart's successor.
