Northampton are the visitors to the Prostar Stadium to face a side who have taken 13 points from a possible 18, losing just once against Gillingham last weekend.
Turner said: "We gave the players a target for the first six matches of the season and we have surpassed that target.
"So we can be disappointed with the defeat at Gillingham but we can also look at the bigger picture, the six-match targets that we set in terms of points, goals for, goals against, the majority of those targets we've achieved.
"It has been a good start and what we start on now is the next six matches and how we react to this defeat."
Northampton will be hoping for a better outcome than when they travelled to Shropshire just under one year ago when the home side ran out comfortable 3-0 winners.
