Rangers thrashed St Johnstone 4-0 to continue their impressive start to the season.

The game was won through goals from Malik Tillman, Antonio Colak, Scott Arfield and Tom Lawrence.

Here's three key talking points from the action on a sweltering day at Ibrox.

Tillman continues to light up Ibrox

He's impressed on every appearance to date and Rangers will be rubbing their hands together having secured an option to buy the 20-year-old. They already look certain to activate the deal with Bayern Munich - such is the impact the powerful kid has had since his debut in pre-season. Built like a tank, he was never going to struggle with the physicality of the Scottish game and he also has the skillset to unlock defences with an array of deft touches and flicks. His goal was a second example of his aerial prowess this week after he leapt like a salmon to grab the tie-clinching goal against USG. Today he bulleted home his header at the back post after being picked out by assist machine James Tavernier.

Antonio Colak the poacher Rangers needed

With Alfredo Morelos far more menacing and prolific in Europe than in domestic football where his highest ever league tally is 17 goals, Rangers have been crying out for a penalty box striker with a ruthless streak. Now they have one. Colak grabbed the crucial second after brilliant work from Rabbi Matondo in shutting down the St Johnstone defence. Colak didn't have a lot of time to react but he spun with great haste to convert with a venom that left Remi Matthews with no chance in goal. At just under £2m he looks an inspired piece of recruitment by Ross Wilson and his team.

St Johnstone's low block not much fun

While the budget disparity between the teams makes St Johnstone's tactical decision to sit so deep understandable, the total lack of threat displayed made for a depressing but familiar spectacle. Saints fans may feel entitled to feel mildly shortchanged in watching their team barely encroach beyond the halfway line in an entertainment-light afternoon from their point of view. And it's not an issue that doesn't affect the hosts either. After a calendar year of punch-for-punch entertainment on the continent, domestic football lacks the same level of lustre. Things will hot up in time of course, but this was something of a cakewalk.
