He also promised them a "fair deal" after the completion of the mega event starting here next month.
Gill statement comes after negotiation collapsed between the administrators and the players, who are staying away from the camp protesting non-payment of their 2009 dues.
"In this situation, I am of the view that an immediate long term solution is not possible. The duty of all players is to continue training and be ready to play the first match of the World Cup on Feb 28 against Pakistan," Gill said in a statement.
He promised, "After the tournament, the ministry of sports will be in dialogue with the new elected management of Hockey India to find satisfactory solutions to all issues, raised by the players."
"I wish to appeal to the players to immediately join training and continue so with full heart till the tournament and focus to win it. I am clear that after the tournament I will do everything possible, to give the players a fair deal," Gill added.
