England are in a dominant position after making 477 and then reducing Australia to 99-5 on day two at Trent Bridge.

Feature: Perfect partners

Andrew Flintoff's first century against Australia - his fifth in Test cricket - was his most significant contribution with the bat for England.

He was composed throughout, and having suffered the loss of Kevin Pietersen in only the fifth over of the morning, there was certainly the potential for England to be dismissed for a score of 300.

But as we saw last summer, Flintoff and Geraint Jones clearly love batting together.

They are perfect foils for each other as Jones scurries the singles that give Flintoff as much of the strike as possible, but also deals severely with anything wide of his off stump.

Flintoff, meanwhile, is a colossus at the crease, and young Shaun Tait was dealt a savage lesson when he was thumped for three fours when the second new ball was taken.

A crucial decision was made by umpire Steve Bucknor when, to the first ball after lunch, he ruled against an appeal for a catch by the keeper against Geraint Jones.

It was a critical moment with Jones on 34 - he went on to score 85 - and a loud noise was evident on the slow motion replays.

But was the sound made by the ball hitting the bat, or the bat hitting the ground?

Either way, England fans certainly did not complain about the decision.

Hoggard bowled arguably his best spell of the series so far

Matthew Hoggard's first delivery. It swung, and that set the scene for some outstanding bowling from England's attack.

Hoggard and Simon Jones found much more movement than any of their Australian counterparts, and certainly more accuracy.

By bowling a full length, they exposed the batsmen's lack of technique at playing the swinging ball.

Hoggard has had a quiet series up to now, but these conditions were tailor-made for him - and it proves that England do have a bowling attack for all occasions.

The manner in which England's bowlers have tormented the Australian batsmen throughout the series suggests the tourists will struggle to avoid the follow-on in their first innings.

Adam Gilchrist is overdue a score, but with the bowlers able to swing the ball both conventionally and in reverse, England hold all the aces.

The delivery from Flintoff that burst through the top of the pitch and hit Justin Langer on the head will cause alarm. Balls like that are rarely a one-off, and it suggests that batting on the final day will be difficult.

This would affect Michael Vaughan's possible decision to enforce the follow-on - if he finds himself in that happy situation.
