Indian skipper Mahendra Singh Dhoni Tuesday clarified that he was not referring to any cricketing fatigue factor per se in the run-up to the World Cup, but rather to the mental preparations required for a warm-up game, something he was not used to.

"It is not fatigue factor but about mental preparation for a warm-up game. It is difficult to prepare like you do for a regular match. I have not played warm-up matches even during the start of my career at school or district level, and all of a sudden, you have to prepare for a warm-up game," he said in the course of a media interaction on the eve of India's second warm-up game against New Zealand here.
