Ashley Williams is pushing to play for Everton this weekend.

Everton assistant manager Erwin Koeman urged caution when asked about the possibility of Ashley Williams making his debut against West Bromwich Albion this weekend, as quoted on the club's official website.

The Toffees opened their Premier League campaign with a 1-1 home draw against Tottenham Hotspur, in which manager Ronald Koeman went with a back three of Mason Holgate, Phil Jagielka and Ramiro Funes Mori, leaving Ashley Williams out of his side.

Williams, 31, signed from Swansea City last week as Koeman looked to shore up a defence that struggled under Roberto Martinez last season.

Fans are understandably keen to see Williams make his debut, but Koeman rested him last weekend having featured for Wales in the Euro 2016 semi-finals - and supporters are left wondering whether they will see Williams in action against West Brom on Saturday.

A proven Premier League centre back, who was one of the league's most dependable centre backs at Swansea, Williams is a key addition for the Toffees, though Everton's defence stood fairly strong against a potent Tottenham attack last week, making it difficult for Koeman to drop anybody.

Koeman's assistant and brother Erwin has been speaking about the situation to the Everton official website, and suggested that Williams needed his rest last weekend having been tired from Euro 2016.

Erwin Koeman suggested that Everton will see how Williams is before the game, and they will be cautious with the Welshman as they don't want him to pick up an injury, much like Aaron Ramsey did last weekend.

"We will have to see because he started training very late after the Euros. He needed his rest," said Koeman. "But he is experienced and knows everything about the Premier League, so we will see what happens this weekend."

"You saw that a lot of players who were at the Euros did not start the first game of the Premier League season. It’s very tough for them because they needed a little rest. You cannot put a player straight into a game after a holiday because then he will get injured. That’s not what we need," he added.
