The first team coach insists the Frenchman is passionate despite his calm exterior.
Relegation is looking like a certainty come the end of the campaign, with an escape similar to previous seasons not looking to be on the cards.
There have been questions of the passion shown by manager Garde, who has remained a calm and collected figure despite the turmoil his side are in.
Black has dispelled those though, saying there is passion with the Frenchman, labelling him a first class individual.
"Rémi is an absolute gentleman. He's very articulate. He's very studious. He's very analytical. I have found him a first class individual,” he told avfc.co.uk.
"He exudes that calmness - and that's not easy in the Premier League when you're in difficulty. He has that assurance.”
"Without doubt, he is passionate. He's been a winner - and he also wants to play football in the right manner. He's an intelligent man. He's studious. But he certainly gets his point across."
While Garde may be passionate as Black says, it is fair to say that is a trait that is sorely lacking in the current squad.
The loss to Liverpool was evidence of that, with them seemingly giving up once they found themselves 1-0 down in the game.
That is inexcusable in a relegation fight, and perhaps Garde should start showing more passion on the touchline in order to get the same response from his players.
