His fitness could be one of the biggest concern for the Indian team management, as he has not been involved in any competitive matches at the international level in recent times. The upcoming T20 matches against New Zealand could give him a perfect platform to prove his fitness and form to his critics, if required. Had it been any other format, his fitness might have been a major factor, but with T20 only scheduled for three hours, he is expected to stand on top of his fitness during those hours.
The Indian selectors know about the value of Yuvraj in the team, especially with the matches being played in Sri Lanka, where he could be used a valuable slow bowler apart from his batting exploits. Another point which scores for Yuvraj's inclusion in the starting 11 is the vacant no. 4 slot in the batting order. Virat Kohli, MS Dhoni and Suresh Raina are no 3, 5 and 6 in the Indian batting order for the T20s. These batting positions reshuffle from time to time depending upon the situation.
A number of players have been tested at the no 4 batting position and no one has delivered to cement his place. Rohit Sharma has been a huge failure. The only player who could give Yuvraj a fight for a place in the starting 11 is Manoj Tiwary who has performed decently when a chance has come through. But, it is Yuvraj's impressive record in world cricket, irrespective of his absence from the game that should grant him a place in the starting 11.
