Holders Celtic cruised through to the semi-finals of the Scottish League Cup and a meeting with Kilmarnock after Liel Abada's double helped them past Motherwell.
Abada tapped home Greg Taylor's cross moments before the break, and then stuck a side-foot volley past goalkeeper Liam Kelly after it.
The Israeli winger then turned provider for Reo Hatate, before his shot off a post fell to Kyogo Furuhashi to tap home Celtic's fourth, as they eased into the last four.

There was rarely a moment at Fir Park in which it felt like a shock was on the cards, as Celtic created a glut of first-half chances before eventually finding the breakthrough.
Kyogo could have had a hat-trick before the break as he cracked a shot off the bar, missed a gilt-edged chance from six yards, and then had another close-range shot saved by Kelly.
Motherwell were ultimately powerless to resist Celtic's movement in the final third, but Steven Hammell's side still had a go in spells only to fail to take the chances that did come their way.
