Kolkata Knight Riders (KKR) captain Gautam Gambhir displayed acute leadership skills in the fifth season of the Indian Premier League (IPL) by guiding his team all the way to the title. But more than that, the left-hander showed that India have a viable alternative to MS Dhoni ahead of the T20 World Cup.By cornering glory in the most prestigious club championship of T20 cricket, that too against Dhoni’s feared Chennai Super Kings, Gambhir has done his credentials no harm. In fact, Gauti has always risen to the occassion, be it for KKR, his Delhi Ranji team or even the Indian national side in one-day cricket.Making Gambhir’s case stronger is perhaps Dhoni’s recent struggles at the international level. The IPL aside, MSD has seemed short of ideas in Tests, one-dayers as well as T20 cricket. Till now, the selectors seemed to have little option but to persist with Dhoni, but Gambhir now could bring the much-needed freshness in leadership and perhaps do for India what he has done for KKR.The T20 World Cup 2012 will be played in Sri Lanka later this year. The hosts take on Zimbabwe in the first match on September 18, while India play their first match against Afghanistan the next day.
