England need another big score from Joe Root in the fifth and final Ashes Test at The Oval.
Root is England's top-scorer in this year's Ashes, scoring 443 across seven innings so far at an average of 73.83, with two hundreds and two fifties.
It is form that has seen him rise to the top of the ICC Test rankings, quite the turnaround considering Root was dropped for the final Test of England's 5-0 hammering in Australia 18 months ago.
