Graeme Swann says England must not let their standards slip against India

Bowler Graeme Swann tells BBC Sport's Joe Wilson that England need to maintain their standards to stay on top of India ahead of the fourth Test at The Oval.

The spinner says India are still a world class outfit and England, who lead the series 3-0, cannot assume they are down and out.

Graham Onions has been called up as bowling cover for Jimmy Anderson, and Swann is pleased to have the Durham paceman back.
