Sunderland goalkeeper Marton Fulop says he will study the video of Liverpool's second goal from Tuesday's match.
The Hungarian-born shot-stopper made an error that led to the Reds second goal in the loss when he knocked down a David Ngog shot into the path of Yossi Benayoun who easily scored.
Fulop said he would go back to the tape to help him improve further.
"I will have to look at the video to judge exactly what happened with the second goal," he said.
"I don't know if I should have stayed on my line or perhaps punched it. I tried to catch the cross, but it was a bit too long.
"I misjudged it and Liverpool scored. This is the goalkeeper's life.
"It is the manager's decision now for Spurs. I will prepare like I'm number one and am playing.
"If he wants to change it, I will have to deal with that. But I felt good in the game last night.
"I made a mistake and, against a good team particularly, it costs you."
