Dutchman Rini Coolen says being reappointed Adelaide United coach for another four years will enable his grand vision to become reality.Coolen has led the Reds from bottom to this season's finals and has been reappointed until 2015 by Adelaide's new owners, who took control last November."I'm very happy because when the new owners came in, I found out that they were looking forward at the big picture," Coolen said on Wednesday."And it was in the same line of thoughts of how I prefer to work."We have already made a lot of good steps this year and there are still a lot of steps to go for the future."For that we need more time and that is what they gave me."Coolen said the show of faith would permit him time to implement his master plan."It gave me a lot of confidence when the club asked me to do this for so many years and I'm happy to do it," he said."So we have to go through a number of processes to make another step and play entertaining football and get results."And also work on developing everyone around the club - and that includes the senior and the youth coaches, the young players, as well as paying a lot of attention on developing the local players as well."Adelaide United chairman Greg Griffin said Coolen's vision was compelling."From his experience, Rini has a great knowledge of the game, I think he has a lot to give us in terms of coaching methods and development," Griffin said."And he's very much on the same page as us in terms of developing the right culture to take this club forward."We decided to make it a four-year deal because, in essence, many of Rini's plans require time, particularly in respect of our junior development program and elite junior athlete programming."It needs time to put into place so that you can actually get the benefit of the work, so a one- or two-year deal would have meant that the junior program would have been greatly devalued."What we want to see is a very effective and high-class junior development program that feeds young South Australians into a Reds shirt."
