England captain Alastair Cook has insisted that he was always "confident" of beating Bangladesh despite almost falling to their first ever Test defeat at the hands of the Tigers.

Bangladesh went into the final day of the first Test in Chittagong needing just 33 runs for a historic win over the tourists, but Ben Stokes took two wickets in the space of three balls to wrap up a 22-run victory.

Despite the close nature of the win in the end, Cook claims that he was "relaxed" on the morning of the final day due to the confidence he had in his bowlers.

"I was fairly confident this morning, if I'm brutally honest. I thought we'd create the chances, the doubt was whether we were good enough to take those chances," he told reporters.

"They might [have been] half-chances. But I thought we'd create enough to win the game so I was fairly relaxed. I did genuinely think 280 was going to be enough, I didn't think it would get as close as that and the way they played spin in particular was very impressive.

"It was a brilliant Test. I certainly didn't think after the first session that it would go to day five. It ebbed and flowed. The crucial moment was probably the beginning of day three when they were 70 or 80 behind with five wickets in hand and we managed to get a lead. That was the crucial difference."

The second and final Test will begin in Dhaka on Friday.
