New Delhi, Aug.21: Yuvraj Singh may not have featured during India's recent 1-0 Test series win against England but the all-rounder is set for a key role when his side take on their hosts in a seven-match one-day international campaign starting with a day/night encounter at Hampshire's Rose Bowl ground today. India is likely to open with Sachin Tendulkar and Sourav Ganguly, a right-left combination of experience and runs.
