Swansea City captain Ashley Williams says Jonjo Shelvey will recover from his mistakes in the 2-2 draw with Liverpool at the Liberty Stadium.
Shelvey put the Swans ahead against his former club, before his slack backpass allowed Daniel Sturridge to equalise.
Another sloppy Shelvey pass led to Victor Moses making it 2-1 before Shelvey set up Michu's leveller.
"We have a game Thursday and then we've got a game Sunday so it doesn't stay with you for too long," said Williams.
"But it definitely hurts at the time."
Afterwards Shelvey apologised to the Swansea City fans but Williams said no one should blame the 21-year-old.
"It's an honest mistake. What are you going to do? You can't have a go at him. I'd rather have a go at someone that didn't give 100%," said the Swans skipper.
"No one's blaming him or anything. It's just one of those days.
"I know more than anyone what it's like to make a mistake."
Shelvey's first error came during a frenetic start to the game and Williams said he and Leon Britton tried to rally round the midfielder who joined from Anfield in a £5m summer move.
As well as the mistakes Shelvey was also booked after clashing with ex-Liverpool team-mate Lucas Leiva
"He plays with emotion and we knew it [the first Liverpool goal] was going to stick with him a bit.
"Me and Leon just tried to speak to him and say 'just settle down, just play simple', but he obviously didn't listen!"
But in assessing Shelvey's overall performance, Williams believed he had a good game.
"He was always willing to get on the ball and try and make things happen.
"I said at the time when we signed it was a good signing for us. He added something that I believe we have never had at this team.
"I think he needs to settle in a bit more to the way we play but that's natural.
"For someone who gets on the ball that much he is going to make mistakes, but hopefully he could be a very good player for us for years to come."
Swansea City now prepare for their opening for their Europa Cup visit to play Valencia at to the Mestalla on Thursday, before resuming the Premier League campaign at Crystal Palace on Sunday, 22 September.
