Duck, Duck, Goose is a traditional children's game in England ( Perhaps Joe root and his team mates might have played a lot in their childhood ).
"Rumaal Chor" game was followed by a serious practice session. At least 3/4 teams in this world cup are equally placed and Team bonding will play a huge role on the road to success.
Who better than the coach knows about it and this is why Indian cricketers went back to pre school days at the Oval Cricket ground ahead of the world cup.
