Benitez was Liverpool manager at the time and although there are no accusations against Liverpool, there are suspicions about their opponents.

"I'm surprised, though it was nothing to do with [Liverpool]," Benítez said. "We went out to win the game, and we did. I didn't remember [anything suspicious]. It was a game we had to win, and we approached it to do just that.

"The fact it was 1-0 means it was quite difficult. I think that it's fantastic that the investigation is taking place, analysing those 300-odd games. If they find something then OK. If not, even better. But it's important to clarify things. I'm very happy with that."
