More from our cricket correspondent Dean Wilson, who's been gripped by that fascinating session we've seen this morning:

It is tight tense, nervous stuff out there in the middle.

The serene progress England had hoped to make was given a sharp jolt when Kevin Pietersen and Alastair Cook fell in quick succession and it is all about recovery right now for Ian Bell and Jonny Bairstow.

The force is with Australia, no question. Their body language shows they are up and up for it. Bairstow in particular looks nervy and far from secure.

This passage of play is what you would call the 'big moment' of this match. You can sense that the winner between lunch and tea could well be the winner of the game.

For Bell it is such an important innings, he's not been in the greatest Test form over the past 12 months, but he is the man on which so much rests.

Everything in this game is possible, but Australia's food will be tasting sweeter right now.
