Half-centuries from Virat Kohli (right) and Suresh Raina propelled India to a six-wicket win that they wrapped up with 10 overs to spare, despite feisty bowling from Steven Finn (3-45).
England batted first but could only rack up 220, Tim Bresnan top-scoring with 45 from 45 balls, before being dismissed with 23 deliveries remaining – leaving Cook staring at a 4-0 deficit.
“I’ve had better couple of weeks, I won’t lie to you,” he said. “But you know when you take over a young side it’s never always going to be that straightforward. It’s certainly a challenge, and one that I am strangely enjoying.”
Cook had to defend Finn, who had strong words with Raina after dismissing him. “I’d much rather the side play on that sort of edge than sit back and accept fate,” he added. “It’s desperation to win.”
