Sinclair has scored five goals in his last two competitive appearances for Villa including a hat-trick in the 5-3 Capital One Cup win over Notts County, and a brace in the 2-2 Premier League draw with Sunderland last weekend.
Of the revitalised Sinclair, Bacuna told the club's official website: "Scotty's doing really well.
"He's trying to find the right space in front of the goal which he's been doing successfully.
"He's hungry and that's really important for us as we need people who want to and can score goals.
"We need to keep going.
"We're working hard in this period without any games and we need to go out and try and win games when we get back on the pitch."
