Former South African skipper AB de Villiers has announced sudden retirement from all forms of international cricket with immediate effect. ABD announced his retirement through a video posted on his Twitter handle.The South African was a part of the Royal Challengers Bangalore squad which was knocked out of the 2018 IPL recently.I’ve made a big decision today pic.twitter.com/In0jyquPOK— AB de Villiers (@ABdeVilliers17) May 23, 2018"I've had my turn and, to be honest, I'm tired," he said."This is a tough decision. I've thought long and hard about it and I'd like to retire still playing decent cricket. It would not be right for me to pick and choose where, when and in what format I play for the Proteas."For me, in green and gold, it must be everything or nothing."Here's how the cricketing fraternity reacted to the sudden announcement.Mark BoucherI remember this young guy on his 1st day out for Proteas... What an inspiration, person and player he turned out to be.

All the best for your future endeavours @ABdeVilliers17, thank you for all the unforgettable memories! pic.twitter.com/9r4AAQDKfj— R P Singh (@rpsingh) May 23, 2018Harsha BhogleMust admit to being a bit shocked by @ABdeVilliers17 decision to quit all international cricket. We knew it was coming but I thought he would give the World Cup another shot.— Harsha Bhogle (@bhogleharsha) May 23, 2018I said in a blog sometime back that @ABdeVilliers17 was the true natural successor to Lara. He too can ask " Did I entertain?" And the answer would be a resounding "Yes. Yes!"— Harsha Bhogle (@bhogleharsha) May 23, 2018When he says it isn't about playing abroad, I wonder if he turning his back on T20 cricket too. There isn't just a lot of money to be made there but much joy to be delivered too. #ABRetires— Harsha Bhogle (@bhogleharsha) May 23, 2018The fans gave @ABdeVilliers17 a second home in Bengaluru but all over India there will be disappointment. He is the most popular overseas cricketer to play in India.— Harsha Bhogle (@bhogleharsha) May 23, 2018Aakash ChopraThe biggest entertainer in the last decade has bid goodbye to International cricket...your absence will be felt, AB.
