Swansea City manager Michael Laudrup is hopeful that defender Ashley Williams will recover in time for their clash with Everton on Saturday.
The 28-year-old is struggling with an ankle injury and midfielder Kemy Agustien, who would have been his replacement, is out with a calf problem.
Williams has been in disappointing form for the Swans in recent weeks and was also part of the Wales side that were defeated 6-1 by Serbia in a 2014 World Cup qualifier this month.
Laudrup, though, is hopeful that he will be able to call on the services of the former Stockport County player for their Premier League game against the Toffees.
"He has had a difficult week and has not been able to do much because of his ankle, but he will hopefully be fit," he said. "It is important for us that our captain is there.
"He had made mistakes but players are allowed to make mistakes and are permitted to have bad games because the important thing is that they give their all and they play in the way we want them to. Mistakes can happen."
The Dane is also aware that Everton will not be easy to defeat even at home.
"It is a big challenge for us against a club who have a lot of continuity on the pitch and off the pitch," said Laudrup.
"David Moyes has been there 10 years so everyone knows exactly what is wanted of them. They are strong with a lot of individual quality, especially on the left side where they are very good with Leighton Baines and Steven Pienaar."
