Gamel says “I have my own methodology of work which has brought success to my teams in the past and I hope I can achieve the same with Fiji. My task is to build for the future and we will need everyone to be involved. We respect our opponents and we know that they are strong. Solidarity, sacrifices, hard work and our pleasure to play will be our weapons. First we build a new style of play and culture in all the national teams, then we develop coaches’ formations, develop a database for national players, improve international visibility of Fiji football, and develop the women’s game in Fiji.”[3]
