The Villa youngster, who has been linked with a move away from the club, has cast doubt over whether he will be in the squad this weekend.
The 17-year-old winger has made the step up to the club's first-team in recent weeks after being an unused substitute on occasion, making his Premier League debut under Remi Garde in the defeat to Tottenham Hotspur and featuring again in a cameo role against Swansea City the following weekend.
However, Green was not included in the squad for Villa's first match under Eric Black after Garde's dismissal for the home defeat to Chelsea last Saturday despite fans appearing to thoroughly approve of his promotion to the senior set-up.
Reports earlier this week suggested that the teenager is a summer target of several top Premier League sides, sparking concerns that Villa could lose the player who is touted by many at the club to be one of the top talents to emerge from the academy in recent years.
Now, Green has seemingly indicated that he has once again been overlooked by Black for Saturday's match against Bournemouth at Villa Park.

The winger tweeted: "It's a long process..." with a symbol of an hourglass and though he was not clear on his meaning, the implication appears to be that he is likely to have to wait for another taste of first-team action.
If Green is indeed left out again by the caretaker manager, it is likely to come as something of a disappointment to Villa fans, who take any encouraging cameos from youth players as a sign that the future may hold more than just the misery endured this season.
Villa are certainties to be relegated to the Championship this season, and their drop can be confirmed this weekend if they fail to beat the Cherries and Norwich City win at Crystal Palace.
