Ten Cate quits Al Ahli after 5-0 drubbing
Ten Cate, who was appointed coach of the United Arab Emirates side at the start of February after leaving Greek side Panathinaikos, spoke after the drubbing by Qatari side Al Sadd on Wednesday.
"I'm deeply ashamed of what has happened. I'm ashamed for Al Ahli Football Club and ashamed for myself. It was the worst day in my career," Ten Cate told the Asian Football Confederation (AFC) website.
"That's why after the game I offered my resignation. My decision is final. I'm a proud man, I hate losing. If I lose I must get the feeling that I did my utmost to avoid it. But if you lose without a battle it is pointless.
"What I saw tonight was not good. There was no fight, no battle. The players didn't fight for each other. They didn't stand for each other."
It was not clear if Ten Cate, who assisted Frank Rijkaard at Barcelona and Avram Grant at Chelsea, had had his offer to quit accepted by Al Ahli.
