The Baggies have dropped to 14th with three losses in their past four outings but the Birmingham City loanee is confident that upcoming matches against QPR, Wigan Athletic and Blackburn Rovers will get things back on track.
"These three games are big for us," Foster told Express & Star.
"You look at who we've played so far and we've acquitted ourselves well against most of the top clubs.
"But the main thing is that we've taken points from those around us.
"Talk of relegation has been banned at the training ground and, personally, I don't think we've got anything to worry about."
