Chennai Super Kings captain Mahendra Singh Dhoni feels that it is hard to "keep up" with younger players in the team but it will be a "big positive" for the 39-year-old if they are not able to point fingers at him over his fitness. Dhoni who retired from international cricket last year admitted that he is not getting younger and getting old and being fit are two difficult things. The former India captain who leads the Chennai Super Kings in IPL has been a benchmark for fitness in Indian cricket.
