The midfielder has recently returned to first-team training.
The talented midfielder was recently banished from the first-team after being pictured by national papers partying after a 4-0 defeat against Everton.
But after two weeks away from action he got back in the mix this week and is all set to contribute in some way to the Arsenal fixture this weekend.
It was an iron fist approach from the Frenchman and former Aston Villa assistant Ray Wilkins is not sure that is the right approach.
He is quoted by the Birmingham Mail as telling beIN Sports:
"He’s a very, very talented young man. He’s a lovely boy, a lovely human being but he lives in a community whereby his mates want to go out, he’s the man and away they go, but Tim had him grounded.
"After the business in the summer, Tim got hold of him and we nailed him down and he was as good as gold. I don’t know how he’ll react (to being frozen out).
"I just hope Remi doesn’t cut his nose off to spite his face because if there is a better footballer at Aston Villa than him, then I’ve not seen it."
Tim Sherwood certainly seemed to be getting the best out of Grealish, but even under his management this season his form was patchy and maybe it is time for a change in tact.
So far he has been allowed a degree of freedom under Sherwood, whilst Paul Lambert simply didn't use him at all.
Garde might be playing his cards right.
By being tough on Grealish but now giving him a chance to prove him wrong on the pitch it might just inspire the talented midfielder into his best form.
Something Aston Villa desperately need in their battle for survival.
