"I think there's two choices: the first choice, to build Aston Villa with Jack Grealish as the main guy and to make sure they spend money on good players to get Villa back to where they should be," Gestede told talkSPORT.
“Or, Jack Grealish could choose to leave to a bigger team because he doesn't want to wait too long to build something, and he wants to play in the Champions League straight away. I think he's got the quality for this.
“It's not an easy to decision. The club have got a contract with him and they've got to decide if they sell or not. I've just read that they've put a very high price for him and it could be difficult to move for him.
“He's got the ability and the talent to play in the Champions League, so that's where he belongs."
