Batsman and Vice Captain of Indian cricket team Gautam Gambhir said that he is delighted at the inclusion of star players Yuvraj Singh and Harbhajan Singh in the national squad for the upcoming Twenty20 World Cup. While speaking to the Media, he said that Yuvraj's presence would be crucial if India is to win the tournament once again. After guiding the Indian team to victory in the 2011 ICC Cricket World Cup, Yuvraj Singh was diagnosed with cancer, turning the purple patch of his career into a horrible nightmare. He underwent chemotherapy in the United States before returning to India in April to continue his rehabilitation.
