Rangers eased their way into the fifth round of the Scottish Cup with a 3-1 win over Cowdenbeath on Wednesday night.

First-half goals from Andy Halliday, Lassana Coulibaly and Kyle Lafferty secured a trip to Kilmarnock next weekend.

Cowden pulled one back through David Cox.

After making eight changes to the side which beat Livingston on Sunday, Gerrard’s fringe players were workmanlike against the Fifers.

With a Premiership clash with St. Mirren to come on Saturday, we look at three things we learned from a cold night in Fife:

Rangers need to adapt to playing without Morelos

Alfredo Morelos was given a rare rest as Jermain Defoe led the line at Central Park.

While Defoe worked hard, he wasn’t as effective as the Colombian at creating chances for himself.

The two have very different styles and many of the Rangers players looked as though they were expecting Defoe to make the sort of runs Morelos normally would.

While Morelos is, hopefully, going to be at Ibrox for a the foreseeable future – the Gers need to adapt to playing without him.

Gerrard’s fringe players need to do more to earn regular starts

The Light Blues made eight changes from Sunday but too few of those who came into the side done themselves justice.

 

There wasn’t anyone who played particularly poorly – maybe Jon Flanagan – but there wasn’t anyone who stood up and took charge either.

If players like Kyle Lafferty want to win a regular place in the starting XI they really need to be doing much better against the team sitting in seventh in League Two.

When Rangers take their foot off the gas it is like watching a different team

The difference in performance when Gerrard’s side are hungry and pushing compared to when they are happy to sit and see a game out is frightening.

Going from the first-half performance to what was on show after the break is genuinely worrying.

Being 3-0 up is one thing but in a team full of fringe players, they should be trying to make a statement.

Cowdenbeath shouldn’t have been allowed to have had anywhere near as much of the ball as they did.

If players can’t perform for 90 minutes, regardless of score or opposition, they are never going to win trophies.
