Buckie Thistle manager Graeme Stewart looks like he's enjoying himself in the visiting technical area.
He's pacing up and down, while constantly dishing out some instructions to his players.
So far, so good for the Highlanders...

The deep free-kick is cleared by Celtic then it just won't sit nice for Max Barry.
Promising though for Buckie.
Celtic 0-0 Buckie Thistle
Joseph McCabe, that's superb.
The Buckie wing-back drives into the Celtic half and wins a foul.
A chance to deliver...
Celtic 0-0 Buckie Thistle
John Hughes
Former Celtic defender on Sportsound
The linesman raised his flag [on Abada] and called the offside.
We could've avoided all of that with VAR.
Say it again, Yogi. Take a weekend aff, VAR.
Celtic 0-0 Buckie Thistle
Brave defending from Jack Murray to make a defensive header and he wins a foul for Buckie.
Celtic 0-0 Buckie Thistle
The flag is up on Liel Abada again and Buckie will take their time getting the game restarted.
Nine minutes played, goalless.
Celtic 0-0 Buckie Thistle
Back to actual football, another Luis Palma corner comes in and Maik Nawrocki heads it towards the back post.
Wide.
Celtic 0-0 Buckie Thistle
After ALL OF THAT... Liel Abada is offside.
The referee went to the monitor as there was a subjective element to it.

He's still at the monitor.
*sighs*
Celtic 0-0 Buckie Thistle
The referee is going to the monitor though...
Celtic 0-0 Buckie Thistle
Liel Abada is surely offside in the build-up anyway...
Celtic 0-0 Buckie Thistle
Liel Abada is down in the box after Stuart Knight smothers in goal.
He wants a pen, which VAR will check.

Celtic in their green and white hoops, Buckie in all yellow.

The disco lights are on at a fairly packed Celtic Park.
What a moment for Buckie.

Buckie Thistle defender Darryl McHardy tells BBC Scotland: "This is crazy. It's unbelievable, I can't put into words how it feels. First time playing here but I used to come down as an Aberdeen fan, so never normally good times.
"When we saw the team we were all like: 'What on earth?' Other than Calum McGregor this is probably the best side they could put out. They've shown us the respect by doing this.
"You don't want to be playing against a B side or whatever, you want the best players in Scotland. It's going to be a brilliant occasion.
"I've had two weeks of sleepless nights and nightmares about Kyogo, last night especially."

The manager, the players, the board and the fans... everyone associated with Buckie Thistle are living the dream here today.
It's fairy tale stuff and they are lapping it up. The weather is absolutely abysmal, but I'm not even sure any of the travelling squad or supporters have noticed.
The Scottish Cup at it's best...
