Celtic 4-0 Morton

That is unbelievable from Kyogo. He is so clinical in those areas. If you give him a half yard to get a shot off he rarely misses. Morton had good numbers in the area but they don't do enough to clear it. His first touch is to get it out his feet, second touch it's in the back of the net.
Kyogo Furuhashi
Oh dear. A horrible swipe from Morton captain Grant Gillespie sets up Kyogo to smash in the fourth goal.
Celtic 3-0 Morton
Liel Abada in the thick of the action again with nice control and a rising shot on the turn, which is well stopped by Brian Shwake.
Celtic 3-0 Morton
A cute pass from Aaron Mooy splits the visiting defence and the busy Liel Abada fizzes the ball across the six yard box. None of his team-mates can get a touch.

He makes it look so easy. He's a tremendous footballer, David Turnbull. It comes from Abada down that right-hand side. Kyogo drags defenders towards him. What a brilliant finish it is. I think that might be curtains.
David Turnbull
Oh, that's a lovely finish...
Liel Abada jinks in from the right, Kyogo cushions the lay-off and David Turnbull just strokes it low into the bottom corner from the edge of the area.
Celtic 2-0 Morton
There are lots of Morton defenders in their penalty area but they're all standing off as Daizen Madea twists and turns to get off a shot. Straight at the goalie though.

They will never stop attacking because there is so much quality in the side. With the rotation of the squad, Ange Postecoglou is ruthless in the manner that he freshens things up.
Celtic 2-0 Morton
Celtic are slicing through Morton with ease now as Liel Abada rolls in a pass for Aaron Mooy, who crashes a shot against a defender before Alexandro Bernabei darts forward to skew an effort high and wide.

Sitting right behind the Morton dug out and manager Dougie Imrie is not happy. He’s pacing his area and shaking his head in frustration.
After the VAR decision went against his side he showed his displeasure to the fourth official. The mistake at the back from Efe Ambrose which led to the second Celtic goal only added to his angst.
Celtic 2-0 Morton
Celtic pop off a series of rapid passes before Liel Abada's curling strike from the edge of the box zips a foot or so over the target.
Celtic 2-0 Morton
Daizen Maeda steals the ball from a dithering defender and slaloms his way forward with real menace, only to lift his shot high over the crossbar.

Efe Ambrose - it wasn't the day to take chances in that area of the pitch. Ambrose tries to keep possession but it's a really poor error, having just conceded a goal.
Celtic 2-0 Morton
Referee Kevin Clancy has his finger in his ear again, checking for something untoward from a Morton counter-attack. Nothing doing this time.
Kyogo Furuhashi
A slack touch from Efe Ambrose is seized upon by Liel Abada, who threads a quick pass through to Kyogo and the Celtic striker pokes it home to double the home side's lead.
Just a quick reminder that only three of the fourth-round ties will have VAR in operation.
This game, and the ones at St Johnstone and Hibernian, must use it as they are televised games at top-flight grounds.
However, it need only be used at other Premiership stadiums if both clubs agree to share the cost or the home club pay to employ the system. Just as is the case with the FA Cup in England.
