Liverpool manager Roy Hodgson is backing goalkeeper Jose Reina to come back strongly after his weekend howler.
The Spanish World Cup winner spilled the ball into his own net to hand Arsenal a draw in the final minute of the Reds' Premier League clash at Anfield on Sunday.
It was a rare error from the 27-year-old, who was the club's player of the year last season.
"If you are a goalkeeper and you can't live with a mistake you make, then you'll never have a career at any level," said Hodgson.
"There is only one certainty in football if you are a goalkeeper, and that is one day you are going to make a mistake which is going to let in a goal. It may cost your team some points.
"When you put your gloves on, you know that.
"If you are a good goalkeeper, it doesn't happen very often and more often than not you come off the field with people congratulating you on winning points for the team.
"It was a mistake, he understands that. We feel sorry for him because he took it hard but he is a strong character.
"Let's hope he's forgotten it as quickly as I have forgotten it."
Reina has a chance to put the blunder behind him as Liverpool take on Turkish side Trabzonspor in the first leg of a Europa League play-off at Anfield on Thursday night.
Another player who will be keen to get onto the pitch will be Joe Cole, who was sent off on his league debut against Arsenal.
With the club having decided not to appeal against the red card, the England midfielder must now serve a three-match domestic suspension.
Hodgson said: "In an ideal world you would have a case for an appeal but with the way the rules are set up you have got very strict codes on which you can appeal.
"We were concerned they might increase the ban and that would have been even worse.
"It is disappointing but these things happen in football."
The unsettled Javier Mascherano will not feature due to a calf injury while defender Daniel Agger will not be risked after suffering concussion against Arsenal.
New signing Christian Poulsen is in contention to start while Fernando Torres is also pushing for a starting place after a substitute appearance on Sunday.
Having led Fulham to the Europa League final last season, Hodgson again intends to take the competition seriously but admits it is not his top priority.
"If you are going to prioritise you would prioritise the league always," he said.
"That might even go for teams playing in the Champions League but we take it very seriously and we will be doing our best to play well and win the game."
