Dundee manager Barry Smith wants his side to replicate their recent first-half performance against Motherwell as they aim to pick up their first home win of the season against St Johnstone.
The Dark Blues produced some of their best football so far against Stuart McCall's league leaders until a late collapse cost them the points.
"In our last home game we were very good against Motherwell who are top of the league," he said. "That's the kind of standards we want to aim for but have to try and maintain that for the 90 minutes."
Dundee welcome St Johnstone who have climbed up the table thanks to back-to-back league wins as well as securing their place in the Scottish Communities League Cup earlier in the week.
Smith is full of praise for their Tayside rivals, but wants his own side to fully focus on their own business.
He said: "Saints are doing really well and they're a quality side. They've picked up recently to put themselves back in the pack, although things are still very tight.
"We respect them but know ourselves what we're capable of on our day which is what we have to concentrate on."
Smith hopes his side are spurred on by the lively atmosphere likely to be created by the derby clash.
He said: "I would hope St Johnstone bring through a decent following because our fans will turn out in numbers as usual.
"These are the kind of games our players should be relishing being back in the SPL."
