“We’ve shown by our CIS Cup exploits what can happen when a team from a lower division meets one from a higher league in cup games. Anything can happen in the cup, and I just hope we don’t fall victim to a cup upset ,” said Owen.

“Ayr United are a decent side and we have had them watched.

“I played alongside two of their players, David Dunn and Jerome Vareille, at Airdrie, and Ayr are going well in the Second Division.

“They could make the play-offs, so there’s a chance they could be playing First Division football next season.

“Saints cup exploits, and the fact we finished second in the First Division last season and are presently holding that position this term, points to the fact we have raised the bar.

“The club has really come on — but we must be aware of teams like Ayr coming here to get a scalp.”

Owen knows how important a part the home fans can play. And went on, “Players respond to encouragement. My lads give 100% and keep going right to the end, a fact illustrated in the last two games when we’ve beaten Clyde and Ross County with very late goals.

“We have a desire to win at St Johnstone and the supporters can help by getting behind the team.”

Willie McLaren has been a target of the boo boys since his move from Airdrie United earlier in the season, but Owen feels Willie can be a major player for the club and has no doubt he’ll turn in some starring displays.

Saints have injury worries for the game.

Martin Hardie is struggling with a calf niggle plus a throat infection and is “a big, big doubt” according to Owen.

Kevin James is a definite non-starter due to his knee problem and, with three midfield men, Ryan Stevenson, Paul Lawson and Darren Sheridan now away from the club, Saints are particularly light in that department.

They’re hoping, however, that the hold up in the move of Derek McInnes from Millwall will be resolved in time for him to make his Saints debut.

Stevenson, now at Ayr United, won’t be facing Saints tomorrow due to suspension.
