Former Aston Villa assistant manager reveals that he feels sorry for the current boss, whom he says must be feeling "lower than a snake's belly".
Villa are seven points adrift at the bottom of the Premier League table, eight points from safety, and suffered their worst defeat of the season on Sunday with a 6-0 thrashing at home to Liverpool.
Wilkins, who was assistant to Garde's predecessor Tim Sherwood for four months earlier this year, says that the Frenchman is in an impossible situation.
He told talkSPORT: "A lot of supporters will say managers can't motivate the players - why on earth should they? Who motivates the manager when he's as low as a snake's belly? He's as low as a snake's belly, Remi Garde, there's no two ways about it.
"I felt for him [against Liverpool] because he picked a team that he thought would fight and would give its all. He looked a shocked man and I felt for him immensely because it's not pleasant to be in that situation.
"Villa they were quite inept with the goals they gave away. It was sad to see. There are ways of losing a game of football and that's not the way to lose a game of football. You go down with all guns blazing. They laid down and died and it was sad."
The humbling against Jurgen Klopp's side leaves Villa with just three league wins all season, two of which have come in Garde's three-and-a-half months months in charge.
The Birmingham club have won three and lost nine of the former Lyon manager's 19 matches in charge in all competitions, and looked doomed to relegation to the Championship.
With Villa having been knocked out of the FA Cup with a 4-0 home defeat to Manchester City in the fifth round at the end of last month, their next match is a trip to Stoke City in the Premier League on 27 February.
