'Captaincy affecting me'

“Well, actually it is getting worst out of me. I am getting very angry on the field, I don’t know why,” Yuvraj said after his side beat Delhi Daredevils by six wickets.
“But hopefully ... as long as we are winning the games, it doesn’t matter what it brings out of the captain, so I am happy,” he added.
Yuvraj heaped praise on Brett Lee. “Lee has made a big difference. Since he came in, we have got better in the bowling department.”
