Ayr United manager Gordon Dalziel admits that the visit of St Johnstone will give his strikers a good challenge.
The Saints are the only team in Britain yet to concede a goal this season and Dalziel reckons that his young team will use that fact as inspiration.
The Honest Men will go into the game missing Paul Lovering (shoulder), and Alan McManus (groin).
Dalziel said: "They've not lost a goal yet, but my young lads will want to spoil that for them.
"I've been delighted with the enthusiasm they've been showing and we'll go into this with some confidence after three wins."
St Johnstone boss Billy Stark will be without striker Peter MacDonald.
The ex-Rangers player misses out with a groin strain although midfielder Ryan Stevenson, who has been suffering from the same injury, should be fit.
Long-term injury victim Alan Main, who suffered a broken leg a year ago, has been playing in Under-21 games recently but is still a few weeks away from returning between the sticks.
The Saints have begun their league campaign in fine form and Stark said: "I'm pleased with the start to the season because we've won four, drawn one and not lost a goal.
"I can't complain because it's difficult to get much better, although Falkirk have managed it. As always it will be a tough game down at Ayr but we're raring to go."
