Everton face an anxious wait to discover the extent of a foot injury sustained by talisman Jack Grealish.

The Toffees beat Aston Villa 1-0 on Sunday to move 10th in the Premier League, just four points off fourth-place Liverpool, with Grealish playing the full match against his former club.

Grealish has made a big impact for David Moyes since joining Everton on loan from Manchester City in August, scoring twice and providing six assists in 20 Premier League appearances.

However, Grealish could well be facing a long spell out, after Everton confirmed he had sustained a foot problem.

"Everton can confirm Jack Grealish has sustained a foot injury," a statement read.

"Jack is currently under the care of the club's medical team and will also be reviewed by a specialist in the coming days."

Everton have been depleted in recent weeks, with key players Iliman Ndiaye and Idrissa Gueye helping Senegal win the Africa Cup of Nations, while Kiernan Dewsbury-Hall, Carlos Alcaraz and Tim Iroegbunam have all been sidelined.

Losing Grealish, however, would represent a huge blow.

Grealish has created 36 chances from open play in the Premier League this term, with only Bruno Fernandes (40) and Jeremy Doku (39) crafting more.

His eight goal involvements lead the way for Everton, as does his tally of 38 chances created overall, with James Garner ranking second in Moyes' squad on 27.

This injury may also scupper Grealish's hopes of forcing his way into the thinking of England boss Thomas Tuchel ahead of this year's World Cup.

Everton face Leeds United in their next Premier League fixture on January 26.
