Alastair Cook said on Tuesday that his decision to retire from international cricket has been six months in the making as the opening batsman prepares for his final England appearance.
Cook, 33, revealed on Monday that he will step away from the England stage following the fifth Test against India at The Oval this week.
England's record run-scorer had been pondering the move for most of the year and eventually made the decision ahead of last week's fourth Test with India, where his country secured a series win.

"It's hard to put it into words but over the last six months there have been signs in my mind this was going to happen," former England captain Cook said.
"I always had been mentally tough and had that edge to everything I've done and that edge had kind of gone."
Cook informed captain Joe Root before the game and head coach Trevor Bayliss while it was going on, but the rest of the squad found out in a emotional speech afterwards.
"I told Rooty before the game and then told Trevor during the game," Cook said.
"At the end of the game I said, 'It might be good news, it might be sad for some, it might be happy for others but it's time and I have done my bit. I will play one more game'.
"There was a little bit of silence, then Mo [Ali] said something, everybody laughed and then it was forgotten about."
Cook will leave the game as England's most decorated player, having maximised his talent to its fullest.
"I can look back and say I became the best I could become. That actually means quite a lot to me," he said. "I have never been the most talented cricketer, I don't pretend I was, but I definitely think I got everything out of my ability.
"Hopefully this week can go well, score some runs and then I can go."
Cook has been given an extra incentive to go out with a century after rock legend Mick Jagger offered a charity reward.
There will be an added bonus for runs scored by England and India thanks to Jagger, who is to donate £20,000 (Dh94,200) to the Chance to Shine charity for any individual century in the fifth Test.
The bowlers are not being left out on either side, with the same amount on offer for a five-wicket haul.
If one of them manages three wickets or any other batsman hits a half-century, that will be worth £10,000 for the charity, who provide opportunities for young people to play and follow cricket through involvement in state schools and deprived areas.
Rolling Stones frontman Jagger said: "I follow England - the game in general, in fact - from wherever I am in the world and thought this would be a fun way to make some money for Chance to Shine."
