Brendan Rodgers has undefeated Celtic Cup record scorched as killer Kilmarnock make holders pay – 3 talking points

Rousing Kilmarnock delivered again to sink Treble winners Celtic 1-0 thanks to Marley Watkins' sliding strike to leave the Treble winners suffering Viaplay Cup woe.

Derek McInnes' side wouldn't be denied and enter the hat for the last eight after the Wales international's perfect run to turn home Danny Armstrong's teasing cross as Brendan Rodgers looked away. The win marks the end of the Irishman's perfect Cup record and likely offers up a dose of reality of what he must improve on before the window shuts. Celtic huffed and puffed but were reduced mostly to half chances and potshots in the frantic final exchanges.

The much-maligned surface looked extra dry upon kick off and, perhaps, it played a part in Celtic star pair Kyogo and Maeda hitting the deck with Swan Lake-like synchronicity. But neither side were put off by the plastic with both teams baring their teeth in a biting opening period which led to chances at both ends.

Corrie Ndaba was left cursing his luck as his looping header hit the roof of the net. The holders, a title they are accustomed to, stepped it up with Kyogo and in-form Matt O’Riley passing up openings. Debutant Gustav Lagerbielke didn’t have long to wait for a flashpoint as Watkins claimed for a penalty. But the Swede was animated as he told the Killie man to get up and that was a view shared by referee Alan Muir plus his VAR officials.

Kilmarnock’s early season hype with results against Rangers and Hearts is justified and that was reinforced here with Armstrong a menace but the Viaplay Cup holders were always on hand to offer a reminder of their threat as Kyogo raced in on goal after an error but Will Dennis was on hand to stand tall and Scottish football's premiere marksman.
