Everton goalkeeper Jordan Pickford apologised to fans for his blunder which handed Liverpool a 1-0 victory in the Merseyside derby on Sunday and insists he is mentally strong enough to bounce back.
The England international misjudged a spinning shot from Virgil van Dijk, pushing it onto the top of the crossbar instead of over which allowed Divock Origi to head home the winning goal in the 96th minute.
"I will say sorry to the Everton fans again, because I know how much it means to them," said the 24-year-old, who also went over to apologise to the visiting supporters at the final whistle.
"As players, we know how much it means to us. Look, you make mistakes every now and again. The ball spun and as I tried to flick it over, my hand hit the bar. I think it is the Everton luck when we come to Anfield.
"It's not something you can learn and train and get better from. It's just a freak incident. You move on and get better.
"There is always a case as a goalkeeper...if you make an error it will lead to a goal. Unfortunately, it has been me today. There's nothing I can do about it now. I'm strong mentally and I will get over it.
"I will be ready for Newcastle on Wednesday. We know we held our own against a good Liverpool side for 96 minutes."
It was a harsh end to a derby in which both Pickford and his opposite number Alisson had produced good saves to keep their rivals at bay. Alisson had some consoling words for Pickford at the final whistle - and that was appreciated.
"I couldn't hear what he said exactly but it was nice and it showed a bit of respect," he added. "That football game was played with respect, there was nothing malicious - just a very good game of football.
"It's unfortunate for me but I think it was a good game for everyone on the outside to watch."
Pickford is determined not to let the error derail what has been a good year for him, having established himself as England manager Gareth Southgate's first-choice by performing well at the summer's World Cup.
"I don't sleep well after many games, really, but we have got a game on Wednesday and I will show people what I can do," he said. "You can't practise what happened there in training. You just have to get on with it and I will show you my character."
