Hull coach Peter Gentle acknowledged his team deserved nothing from the 30-4 defeat against Catalan Dragons in Perpignan.
The Black and Whites arrived in the south of France with nine wins from 10 games, including a brilliant victory over Leeds, but they failed to rise to the occasion in southern France.
"We were second best in all departments tonight and they were just too good for us," Gentle said.
"Our completion rate was horrendous, terrible - whichever you want to call it. There wasn't one part of our game that we were on top of and the scoreline reflects that.
"They were very good tonight, but we gave them plenty of opportunities. They're a very talented side and always have the ability to hurt us and if you keep putting your chin out, you're going to get hit. And we did that plenty of times."
Catalan coach Laurent Frayssinous was full of praise for his young players following the emphatic home victory.
"It's a good result for us," Frayssinous said. "I'm very happy. I've been waiting for a big performance from us against a top-four side at home for a long time.
"Tonight we got it, especially defensively - we were pretty good with that.
"They have to keep working hard on their consistency and the quality of their performances, but I'm very happy after tonight."
