India clinched their first Test win at the historic Lord's in nearly three decades after riding on Ishant Sharma's inspired spell of fast bowling to take a 1-0 lead in the five-match series.
India registered their first Test win at Lord's in 28 years -- only second win in 17 Tests here -- after 'Kapil Dev's team achieved the feat back in June 1986 winning by five wickets.
"I haven't had any tougher times in my career than at the moment. It gets harder and harder the longer it goes on. But I don't think walking away from it would be the way to go," Cook said defending his decision to stay on as England captain.

"A tough loss, in good conditions for us, does keep making it harder - and not scoring runs is getting tougher and tougher. It is hard, a tough job when you're losing games of cricket and you're not scoring runs. If I'm not scoring runs by the end of the series, and we're losing more games, then I'm clearly maybe not the man," he added.
