Bacuna has received words of encouragement from Lambert after struggling at right-back against Stoke.
"Bacuna has been playing really well," said Lambert.
"I don't think anybody did themselves justice last weekend, but I think Leo's been playing well and he's come up with some vital goals.
"Leo's form's been really good of late and he wasn't the only one that fell below his standards last week. They all did and they got punished."
