In the film ‘Catch Me If You Can’, there is a theory advanced that the Yankees always win because the other team can’t stop looking at their damn pinstripes.

Rangers may have turned up at Cappielow earlier this season in their unfamiliar red away kit, but their reputation seemed to have a similar sort of paralysing effect on their newly-promoted opponents.

By the time the Morton players woke up to the fact they weren’t playing a team of super-men, the game was long ended as a contest.

In the return fixture at Ibrox though, dread gave way to a healthy respect, and a barnstorming 'Ton performance saw them leave Govan with a well-deserved point.

Come Monday night, their manager Jim Duffy is hopeful that his players can catch the league-leaders off-guard again and perhaps even go one better.

“There was probably an element of fear about us in the first game,” he admitted.

“We had just come up from League One and all of a sudden you’re playing Rangers.

“There’s a huge gulf in class and we were probably a wee bit apprehensive and fearful going into that one, seeing how much they were up for it rather than taking part in the game.

“By the time we took part in the second-half the game was beyond us, whereas the next game around we competed well with them.

“Even if we had lost that game I think we would have still taken a lot of credit from it simply by having a go and making Rangers work for it.

“What we said to the players is that if Rangers are good enough to win, then fine, but at least make them work for it and don’t hand them it on a plate.

“If Rangers play at their very best, Rangers will win the game. There’s no question about that.

“That’s not being pessimistic, that’s being realistic in terms of the quality that they have.

“But if we can be organised, well-disciplined and work hard then we might be able to throw a spanner in the works.

“Every week someone will say ‘there’s a coupon-buster for you’, so let’s just hope that Morton can be the coupon-buster on Monday.”

Duffy was angry with his players following their performance at Alloa last week, where they were fortunate to have the match abandoned due to snow while trailing by a goal to nil.

He knows that his players will be up for the match against Rangers come Monday night, but he has warned them that the same level of application is required in every match they play.

He said: “To be honest I’m probably more disappointed with the way we played at Alloa than I would be if we played like that against Rangers on Monday.

“Rangers are the Hollywood game when the profile and the spotlight is on Rangers, we understand that because of the size of the club.

“We understand that these games take care of themselves, but from our point of view it’s the games against Alloa that we have to be equally ready for.

“When you play any big team that has better players and a level that on their day is hard to match, then you’ve got to be well-organised first and foremost, ready for the challenge and be brave on the ball.

“You can’t just go and kick the ball away and hope that Rangers don’t produce, you still have to have a determination to play.

“If we can do that, then you never know.”
