The final is a rare sporting event between the South Asian nuclear rivals. New Delhi had stalled bilateral sporting relations in the wake of 2008 terrorist attacks on Mumbai, which India blamed on militants based in Pakistan.
Pakistan's cricket team did play a short limited over series in India earlier this year -- their first since 2007 -- but that proved to be a one-off, as heightening tensions on the Line of Control in the disputed Kashmir region derailed the peace process.
"I am happy that kids of below 19 years are starting this with the final," Singh told AFP. "I wish the oneness back between us and that we give a message of peace to New Delhi and Islamabad."
Singh said he feels Pakistan is his second home.
