New Delhi: Former captain Rahul Dravid feels it is time for Zaheer Khan to start deliberating on his future as it would be difficult for the senior pacer to survive the rigours of five Test matches when India tour England later this year.

Zaheer, who made a comeback to the Test team during the disastrous tours of South Africa and New Zealand after a long injury lay-off, failed to trouble the batsmen. Although he bowled 51 overs and took a five-wicket haul in the second innings of the Wellington Test against New Zealand recently, he looked far from impressive.
