Meanwhile, former Manchester United goalkeeper Peter Schmeichel says Villa should never have sacked Tim Sherwood – the man Garde replaced back in November.
Former Tottenham coach Sherwood guided Villa to the FA Cup final last season and helped them avoid relegation.
But he lasted just four months into the new season.
“I’m shocked that you give a manager a job in a very difficult situation, that he hasn’t put the club in, and then you give him that little time to solve it?” Schmeichel told Sky Sports.
“They should have done their due diligence and got it right back then.
“Tim Sherwood was well capable of getting Aston Villa out of trouble, but they didn’t think that and now they’ve gone down the route of sacking yet another manager and history proves that doesn’t help.
“So, it’s a shock and then again no, because that’s the way football has been going for quite a while.”
