Celtic should be able to still dominate midfield because it's almost almost a three v two in there but Zak Rudden's doing a good job.

He's the one that's now been given the job to drop back on McGregor and still pick his moment to go and press and it's working well for Dunfermline.

Kelechi Iheanacho, who scored twice in the semi-final win against St Mirren, replaces James Forrest.

Alfons Amade replaces Nurudeen Abdulai for Dunfermline, too.

Arne Engels sends an inviting low ball to the edge of the six-yard box which goalkeeper Aston Oxborough just gets to first.

Kelechi Iheanacho looks like he's going to join the Celtic attack.

He's made a habit of making an impact from there...

Those three Pars changes at half-time have completely changed the feel of this game.

The Dunfermline supporters are re-energised and it's the Championship side who are dominating the Scottish champions.

The next goal will determine whether Celtic can cruise or whether their opponents can come roaring back.

Celtic defender Auston Trusty is booked for bundling down Chris Kane out on the left-hand side.

Could be Kane, or is it prime R9? Hard to tell right now.

Matty Todd's free kick is headed over by Chris Kane. Apologies I think I got Kane confused for Zak Rudden on the last play.

Chris Kane and Zak Rudden immediately in and about it.

The former tries to rouse the Pars support after winning a corner.

This bright restart has got them going...

That's what Dunfermline's got to do. Neil Lennon's made the changes. He has to go direct. Set pieces are always an opportunity for any team.

Much, much better.

Ooft, great start from Dunfermline. Jeremiah Chilokoa-Mullen surges down the right and wins a corner.

In it comes and Nurudeen Abdulai has a chance to head home but gets his effort wrong.

It's very, very brave. Two strikers and a right wing-back coming on.

They might change shape. They need to go for it, they've got nothing to lose.

We're under way again. It would be a miracle if Dunfermline come back from this situation.

Neil Lennon has made that triple substitution Amy was talking about.

Chris Kane, Zak Rudden and Shea Kearney have all been going through some pretty rigorous warm-ups for the last 10 minutes or so.

Wouldn't be surprised to see them at the start of the second half...

Right, Amy can give us a bit of info on the Dunfermline bench because changes are incoming.

It's going to be hard for Dunfermline, because Celtic fancy it today. You can see it, short and sharp one-twos, the willingness to run in behind.

It's a scary thing when there's pace all over the park and you're playing a back five.

Neil has tried to go aggressive in the first couple of minutes and they almost got a goal, but after that the tiredness crept in.

This will need to be the best team-talk Neil Lennon has ever given in his life.

His side has been totally dominated by the champions and will need to find at least two goals if their afternoon is not to end in Hampden heartbreak.

You have to admire Celtic's energy. They've won their last eight games in a row to keep their league and cup double dream alive.

They're now just 45 minutes away from making it a reality.

Former Dunfermline Athletic manager on BBC One

It's difficult to see a way back for Dunfermline at the moment, Celtic are in full flow.

The opening goal was the turning point, and they've kicked on and dominated the game from there.
