The Australian has netted three goals in as many games against Rangers this season.

The warning signs are clear for Rangers and they are extremely fortunate not to be behind with Moussa Dembele very unlucky with his early volley off the upright.

Brendan Rodgers’ side are playing with intent. They have so much possession and are easing into the style of play that suits them.

Tactically, Rangers may need to tinker to get up the pitch. They surely can’t allow Celtic to keep coming at them.

Alfredo Morelos earns a foul as Kristoffer Ajer sends the Colombian tumbling. However, James Tavernier's set piece is poor and cleared by the boot of Olivier Ntcham.

Old Firm partnership: players from both sides join ranks to burst the balloons on the pitch.

A few well-placed stamps takes the air out of the party balloons... and we're ready to go again.

A minute later, it's Olivier Ntcham who has an effort on goal but it's high, wide and not very handsome.

Frenetic stuff at Hampden in the opening 10 minutes. It remains goalless.

Sitting close to the Rangers supporters, you sense a genuine belief that their side can damage Celtic.

This is a one off and a chance for the Ibrox side to really arrive under Graeme Murty.

In contrast, Celtic know how close they now are to the double-treble. It has never been done before and no matter the context, that would be historic; another chapter in the tenure of Brendan Rodgers’ success story if they go on and do it.

The atmosphere is already electric. It is about who handles that best and which team shows most will to win.

Both sides have all the motivation they need. It could be a memorable occasion.

Here they come.

Both sides come down the tunnel and onto the Hampden turf and into a wall of noise.

The national stadium is a riot of colour.

Brendan Rodgers and Graeme Murty share a quick word and a handshake.
