The Baggies have made a positive start to the new season, having amassed 14 points from their opening seven matches.
Despite impressing many with the way that they have begun life under the management of Steve Clarke, Foster is adamant that beating off the threat of relegation remains the target.
"The target is 40 points," he told the Express & Star. "Once we get to 40 points only then can we start to reassess things and start looking at things differently.
"Let's get safe first. If we do that and still have five, six or seven games left, then we'll move on to other aims onwards and upwards.
"But there are probably about 14 teams in this league who want to just get safe. The top six will have other battles on their minds, the rest of us are in a scrap."
West Brom are currently sixth in the Premier League table.
