The 43-year-old says that he did not think his men would defeat Guus Hiddink's outfit so easily at the Turk Telekom Arena, but believes the job is not yet done
The visitors strolled to a 3-0 victory against a distinctly toothless Turkey outfit, but addressing the press after the game, Bilic confessed that he did not foresee such a convincing scoreline, but credited his players for putting in such a performance.
"When you come to such a stadium, nobody expects this score. We knew they were easily affected like us. Then the early goal gave us an advantage," he told the press after the match.
"Turkey passed the ball well in the first half, but instead we scored the second goal. Then we decided that we'd try to find another goal after half-time.
"We deserved to win by even more goals. It was fantastic. I want to congratulate all my players. They played the whole match without making any mistakes. It was really amazing.
Despite having a stranglehold on the tie, Bilic admitted that he did not believe his side were certainties for Euro 2012.
"We have some problems with injuries so a lot of our players will not play in Zagreb on Tuesday. Nothing is over yet. It is half-time. There is a hard task in front of us."
