Kwesi Appiah says players who are called into the national team will need to abide by a revised rule-book geared at ensuring team discipline.

The Black Stars coach who is set for a contract extension with the Ghana Football Association admits that more will go into his management of the team in future.

Ghana's team were mired in off-field issues at the World Cup which led to the expulsion of two players from camp in Brazil and their subsequent suspensions indefinitely.

However, Appiah is taking pre-emptive action for the future to avoid off-the-field issues.

"As we look ahead, I will look for committed players and we will try not to tolerate indiscipline and anyone who will bring our efforts down.

"Players who come in will be made to sign contracts to forestall any problems like it happened [in Brazil]. The contracts will spell out clearly camp rules and all other conditions," Appiah said.

Appiah is eager to encourage more communication with coaches in the domestic league to provide detailed background information on players.

"I am looking to add up to my technical staff," he said.

"We will communicate with local coaches to help provide much information on players.

"I am waiting for the local league to start and I will keep an eye on the players abroad."
