Aston Villa boss Tim Sherwood insists Jack Grealish is not for sale.

Sherwood does want more work ethic from Grealish, but believes his skill on the ball and big potential would warrant a monumental price-tag.

"I wouldn't want to sell Jack Grealish for £60m today. I know what he could possibly be," said Sherwood. "What looks expensive this year might not be expensive next year.

"That Liverpool game was huge with a lot of expectancy and pressure, it didn't faze him, he grew more.

"He is certainly a type of player we have seen at the very top level for the likes of Liverpool and in the past for Aston Villa, we have to recognise that.

"He's not a shop window job, he's our player, and we couldn't put a price on him. I certainly wouldn't."
