Morientes has told Liverpool fans to keep an eye on his face during the warm-up to see how confident he's feeling about scoring at the Millennium Stadium this weekend.
"I never have a clue if I'll score before a game but from the moment I set foot on the pitch in the warm-up I know if I feel right or not," he said.
"Sometimes I get a feeling in the warm-up that I'll score, but also there are times when I feel lousy and still score a couple. But if you see me smiling in the warm-up on Sunday then you know I feel good!"
See if you can spot it!
