Swansea City manager Michael Laudrup has backed defender Ashley Williams to recover from his mistake against Aston Villa last weekend.
The centre-back gifted the hosts their second goal at Villa Park on Saturday to condemn the Welsh club to their first defeat of the new season.
"It's always difficult when people get used to you playing so well," said Laudrup.
"People say 'He never makes mistakes', but I can say for sure that nobody does not make a mistake at some time."
Swansea continue their second Premier League campaign on Saturday when they host Everton at the Liberty Stadium.
