A red-hot Celtic side was drawn with a struggling St. Johnstone side in the fifth round of the Scottish Cup.

Celtic were in total control right from the start with two first-half goals from Scott Sinclair from great link-up play in the third minute and Scott Brown added a second with an absolute rocket into the top corner after nine minutes, bringing an end to 104 games without a goal.

Celtic were utterly dominant, but St. Johnstone lacked energy until a decent spell towards the end of the opening half of play.

In the second half, Celtic remained dominant with a James Forrest goal on 52 minutes, while Scott Sinclair added another two minutes later before he capped off the day by completing his hat trick in the 89th minute.

Celtic are now 24 cup matches and St. Johnstone have now lost five straight.

Celtic will find out who their quarterfinal opponent will be tomorrow.

Here are four findings from the match.
