Half-time change for Rangers as Thelo Aasgaard replaces Jayden Meghoma.

Attacking switch and a change of shape to a back four.

On Callum Osmand's injury, Celtic interim boss Martin O'Neill added: "He's pulled a hamstring. He's very young, it's never happened to him before, so he doesn't know.

"He was distraught because I think he was just trying to get his career going, but if everything works out well, he'll recover from that and then start again."

O'Neill confirmed Arne Engels "also felt his hamstring".

• Midtjylland scored three goals in the first half of a major European game for the first time.
• Midtjylland remain unbeaten against Celtic in Europe (W2 D1) and Celtic have failed to win any of their last eight games against Danish clubs (including qualifiers – D3 L5).
• Celtic faced 15 shots in the first half of this match, the most they’ve conceded in the opening 45 minutes of a European game since November 2012 (17 v Benfica in the Champions League).

Aberdeen manager Jimmy Thelin: "The way the players behaved today as a team, the tactical discipline and we got good opportunities in transitions.

"It was two big chances - we had one and they had one at the end.

"We are going in the right direction. We need to keep working.

"[Dylan Lobban] has worked so hard. Sometimes when you get an opportunity, you have to take it and he was one of the best players on the pitch.

"It's important to be in European competition every year and we should never give up.

"Now it's about recovery and doing everything we can to get the players ready for the next game."

Celtic interim manager Martin O'Neill: "It was a tough evening. There's no question about it. We were well in the game for half an hour.

"We conceded two goals within a minute, or 90 seconds of each other. The game goes away from you very, very quickly. They score a third after seven minutes and it's a long way back.

"In terms of European football, they're a very fine side. There's no question about it. They're strong, physically, very, very strong. It was something I knew anyway because of seeing them a couple of weeks ago.

"Disappointing, but I thought we showed a bit of character in the second half. We could have gone under, it could have been any sort of score, but the players, I thought, pulled themselves together, pulled it around a bit and showed some character and resilience, for want of better words."

Before we turn our attention to the second half at Ibrox, let's get some reaction from the Celtic and Aberdeen camps.

It was a miserable night for Martin O'Neill but a positive evening for Jimmy Thelin.

Not for the first time this season in the Europe, there are loud boos from the home fans on the referee's whistle for the break.

I must admit, when Roma scored early and then had a couple of further chances before the second went in, my mind flashed back to the horror show Rangers had here at home to Club Brugge.

The Belgians were three goals up in 20 minutes in the Champions League qualifier. It's not been quite on that scale here, but Roma look the best side to have played here since Nicky Hayen's impressive outfit.

There is much for Danny Rohl to do at the interval. Expect some changes in the Rangers side that emerges for the second period.

This season there has certainly been a huge drop-off, Alex, but this club and a fair few of these players got to the last eight of this competition just last season.

And another helping of boos.

Clinical Roma go into the away dressing room with a two-goal half-time lead.

Rangers have a mountain to climb.

The Rangers fans are furious Djeidi Gassama hasn't been awarded a free-kick wide on the right.

And here come Roma...

The move ends with goalscorer Matias Soule curling just wide of the far post.

Then come the boos.

Rangers have to keep playing to get the next goal.

If they get the next goal, anything could happen.

You can absolutely see how this Roma side is challenging at the top of Serie A.

They're just a point behind league leaders Napoli, replete with Scotland internationals Scott McTominay and Billy Gilmour of course.

They're so composed on the ball, have technically gifted players all over the park and have a manager on the touchline in Gian Piero Gasperini who won this trophy in 2024.

That was brilliant play on the right-hand side from Rangers to get in behind the Roma defence.

Rangers almost pull one back instantly as Djeidi Gassama's cutback is saved and Mikey Moore's follow-up attempt is blocked at the last second.

What a nice goal that is. Lovely, lovely football from Roma.

No panic, slicing through their hosts. A calm finish into the corner.

It will take a momentum shift of huge proportions for Rangers to get anything from this game now.

John Souttar can't let that happen.

He must be aware of where the centre-forward is, and he lost his way completely.

Rangers survive a spell of Roma pressure as Jayden Meghoma clears a dangerous cross.

All a bit easy again, though.
