Swansea City boss Francesco Guidolin cannot guarantee Ashley Williams will be staying.

The club captain is a target for Everton as they prepare to lose John Stones to Manchester City.

Williams has already seen one offer from Everton turned down, but the Merseysiders are expected to try again this week.

"I do not know the future, but right now he is training with us," said Guidolin.

Everton are confident doing business with Swans over a price of £12 million.
