Legendary Indian footballer Bhaichung Bhutia on Thursday called for strengthening the game at the age-group level, saying that it’s impossible for the senior national team to do well internationally otherwise.

Bhutia, who has played over 100 games for India and scored 42 international goals, also asked the All India Football Federation, state associations, I-League and ISL clubs work at the grassroots for the development of the next generation of players.
