Former India captain MS Dhoni turned 40 today and understandably social media sites such as Facebook, Instagram and Twitter have exploded with wishes for India?s World Cup winning leader. However, things took an ugly turn when former India batsman Gautam Gambhir decided to update his cover picture on Facebook. While Gambhir celebrating his half-century in a muddy Indian jersey from 2 April 2011- the final of 2011 World Cup, where he top scored with 97 ? is part of India?s cricketing folklore, the timing of his social media update which coincided with Dhoni?s birthday, who finished that match for the team and remained unbeaten on 91, is being questioned by some fans.
