Alastair Cook has admitted that recent results have “not been good enough” but insists there is no question of him resigning the England captaincy if things go badly against India.

England haven’t won in eight Tests, a sequence stretching back to their 74-run victory against Australia at Chester-le-Street in last August’s home Ashes series.

Meanwhile it is more than a year since opening batsman Cook scored the last of his England record 25 Test hundreds.

And with England recently going down 1-0 at home to Sri Lanka after a 100-run defeat in the second Test at Headingley, Cook’s tactics have come in for severe criticism.

Cook said on Tuesday he was thick-skinned enough to cope with the flak that had come his way as he surveyed England’s prospects ahead of the first of a five-Test series against India starting at Nottingham’s Trent Bridge ground on Wednesday.

“I think you have to be determined and stick to your guns. We all know you are judged on results and results have not been good enough.

“If we turn it round and win games of cricket things will be different”.

Asked if he could survive as captain were England to lose the series with India, Cook said: “I am not in charge of anything like that. I concentrate on doing the job which I’ve been asked to do.

“I’m incredibly proud to be England captain. I have thrown everything into it and continue to. Until that day the selectors decide I’m not the right man for the job, I will continue to”.
