The linesman who allowed Luis Garcia's goal to stand in Liverpool's Champions League semi-final win over Chelsea has stood by the decision.
Chelsea boss Jose Mourinho claimed "the linesman scored the goal" after Roman Slysko decided the ball had crossed the line before William Gallas cleared.
But Sylsko told the Evening Standard: "I am 100% convinced it was a goal.
"I believe my decision was correct. I saw it clearly. I was adequately positioned for the situation."
However, Chelsea keeper Petr Cech is not convinced Slovakian official Sylsko was in the right place to see if it was a legitimate goal.
"The linesman was standing in such a position that he simply could not see the ball as Gallas blocked it with his body," Cech told Czech reporters.
"I was surprised the referees decided the goal was scored, when they could not see it.
"I asked him (the assistant referee) how he could be so sure that it was a goal."
Liverpool boss Rafael Benitez argued that even if the goal had not been given, the Reds should have been given a penalty for Cech's challenge on Milan Baros in the lead-up.
But Cech added: "I just occupied the space. Milan hit the ball and then he jumped into me. In my opinion it could not be a penalty."
However Baros disagreed.
He told the Czech News Agency: "At least it should have been a penalty. He flew at me, I think he even did not hit the ball. But it is not important now."
Mourinho could not hide his annoyance that Garcia's goal had been allowed.
"To give a goal, the ball must be 100% in and he must be 100% sure that the ball is in," he said.
"My players say it was not a goal.
"Only one person decided the future of the teams and of players who have never played a Champions League final.
"It's very strange. It was a goal from the moon or the Anfield Road stand, I don't know where.
"But I respect that, I make mistakes, players make mistakes and he made a mistake. That's life."
