UEFA licensed coach, Nana Agyeman, has cautioned the players of the National team, the Black Stars, not to engage in any sexual conduct (or misconduct), as that could have a toll on them and affect their performance in subsequent matches.The players have been given a 24-hour break from camp, after they have impressed Ghanaians with their spectacular performance which saw them beat Morocco 2-0 to top Group A at the ongoing Ghana 2008 tournament.Nana Agyeman is cautioning the players not to spend their energy on other things but conserve it for the national assignment ahead of them.He said, "they must remember that they still have about 50 per cent of work to do", adding that it was important for them to conduct themselves well and not do anything that had the potential to adversely affect their performance.The Black Stars play their arch rivals the Super Eagles of Nigeria at the quarter finals stage of the competition on Sunday, February 3, 2008.
