Indian cricketer Gautam Gambhir on Tuesday announced his retirement from all forms of cricket. The 37-year-old, who represented India in 58 Tests, 147 ODIs and 37 T20Is, made the announcement on social media.The most difficult decisions are often taken with the heaviest of hearts. And with one heavy heart, I've decided to make an announcement that I've dreaded all my life. Gambhir thanked his coaches, teammates and family members for standing by him. "At some stage, I would like to shed the retired cricketer's tag and would like to recycle myself to be useful for something else in cricket and beyond. Let's see," he added.
