Celtic's superb defensive performance was the most impressive aspect of their massive 2-1 derby win on Sunday, according to journalist Kieran Devlin.

The Lowdown: Celtic enjoy huge win

The Hoops knew how enormous three points at Ibrox would be on Sunday afternoon, even though avoiding defeat was the primary objective.

Ange Postecoglou's side went one better than that, recovering from an early deficit to seal a priceless victory thanks to goals from Tom Rogic and Cameron Carter-Vickers.

In the second half, Celtic defended for their lives as Rangers desperately tried to find an equaliser, the visitors putting their bodies on the line and making countless blocks.

The Latest: Devlin hails Celtic defence

Taking to Twitter on Monday as he shared a corresponding article from The Athletic, Devlin lauded the defensive performance and character on show from Celtic at Ibrox, saying:

"This Celtic get due praise as entertainers, but their other face deserves credit. That of scoring late winners, grinding out hard results, matching Livingston's physicality, defending their box to the last man at Ibrox. Yesterday was about their character."

The Verdict: Defence was crucial

Devlin is right to focus on the brilliance of Celtic's defensive work on Sunday, with Postecoglou's men producing a heroic effort, both as a team and individually.

The likes of Carter-Vickers and Carl Starfelt were particularly brilliant at the back, making a combined 20 clearances and six interceptions according to Sofascore, which sums up their Herculean efforts in defence.

Titles can be effectively won on such days with performances of that ilk, and if the Hoops go on to clinch Premiership glory next month, this win at Ibrox will perhaps be seen as the most pivotal day of the campaign.
