St Johnstone captain Dave Mackay warned against complacency ahead of the Tayside derby against his struggling former club Dundee at Dens Park.
Rejuvenated Saints have won three and drawn one of their last four matches after they slumped to the bottom of the Clydesdale Bank Premier League following their poor start to the season. Meanwhile, Dundee have replaced the Perth club at the foot of the table with only one win in seven games.
"If we turn up with a poor attitude thinking we are going to walk that game then we are in real danger, it is not going to happen," he said.
Mackay, 32, who started his career at Dundee when current Dees boss Barry Smith was skipper, told Press Association Sport that he will make sure they are fired up.
"It will be a very tough game. It is a derby as well, Barry will have his players up for it so we will be wary of them," he said.
"The SPL is so tight than any team can beat any other on their day.
"We are about four from the top and four from the bottom, it is so tight.
"A couple of weeks ago people were starting to think St Johnstone were in danger of relegation but you win a couple of games and everything is rosy again."
Mackay insists Saints' early season results did not reflect performances but pointed to a tighter defence as the main reason for the turn in fortune. He said: "If you don't concede goals you give yourself a better chance of winning games.
"We have lost only two goals in the last three games compared to previous games where, when you are shipping two or three, it gives you an uphill battle."
