Garde took charge of the Villans’ training for the first time last Tuesday, and he has quickly attempted to make a difference at the club.
Sinclair says that the French boss has immediately been working on making the side more organised, and he wants all his players to be together for the relegation battle.
“It’s been an interesting week,” Sinclair said. “The new manager has come in and got his points across.
“He’s just been working on team-shape, togetherness and making sure everyone sticks together – which is what we have got to do.”
Garde’s impact at Villa was immediately recognisable, as his side made an excellent start under his stewardship.
The Claret and Blues drew 0-0 with Manchester City yesterday, and they looked a much more organised team than they have over the campaign so far.
Villa rode their luck at times, but they earned credit for the way that they stifled City’s attacking threat, and a point was reward for their efforts.
Villa will now be hoping to build on that display in the coming weeks, as they look to climb out of the relegation zone and towards safety.
