There was a dramatic end to the fourth day at the Oval in Adelaide as Kevin Pietersen took the wicket of Michael Clarke with the final ball of the day .
This was Pietersen's first wicket since July 2008 and left Australia 137 runs behind England with six wickets remaining .
Pietersen had earlier scored a career best Test score of 227 and his late intervention with the ball has given England a real chance of winning this Test .
The weather forecast for the final day is mixed with some rain forecast but England will have the momentum going into the final day to pull off a famous victory .
