The former Dutch international was full of praise for his side who brushed aside the Singapore U16 4-1 in the Lion City Cup final
“I am very happy and I think the boys made a great achievement today,” said Kreek.
“In the beginning of the match, Singapore played very well and caused us a lot of problem.
"But as the match progressed we took over control of the game and at the end of the day, we deserved to win.”
Although his team had won convincingly, Kreek was not too pleased with the performance at the early stages of the game.
“At the start we did not play too well because we lost the ball too early and that gave Singapore chances to counter-attack," added the Dutch coach.
"We could not play our own game and in the second-half we managed to improve our game.
“Singapore’s defence was also very good at the early stages but in the end we showed how good we are.”
Kreek also touched on his academy’s philosophy and team selection adding: “We try to develop all the players we have in our academy and if we come to a tournament such as this, it’s very hard for the kids [to play consistently] in this condition, so we need [to use] all the players in the squad.”
“The win is the achievement of all 18 players and not of just a few."
Besides clinching the championship, Ajax also swept the individual awards with team captain Abdelhak Nouri winning the Most Valuable Player award and Ezra Walian clinching the Top Scorer award with seven goals.
