Is that the weakest bench in Man Utd’s Champions League history? And what is the point of three keepers on the bench!?

Real Madrid 0-0 Union Berlin
Another chance for Joselu, that's his fifth of the night. Jude Bellingham's cross is lovely, Joselu darts in front of his marker, gets a good contact, steers it goalwards but just past the post.
Union Berlin ten minutes ish away from a fantastic point at the Bernabeu.
Real Madrid 0-0 Union Berlin
Leonardo Bonucci, the 36-year-old on his debut for Union Berlin, is taken off with 10 minutes to go and doesn't look too happy.
Paul Jackei is on, so too David Datro Fofana, on loan from Chelsea, with the 20-year-old Ivorian forward replacing Sheraldo Becker.
Brahim Diaz replaces Luka Modric for the hosts.
Real Madrid 0-0 Union Berlin
Real Madrid want a penalty for a potential handball from Danilho Doekhi, sliding in to block Joselu's strike. Nothing happening from referee on the pitch or in the VAR room.
Correct decision.
Real Madrid 0-0 Union Berlin
Rodrygo crosses from the right and Leonardo Bonucci shows he is still a quality defender, sliding in at the near post to get the ball behind for a corner with a brilliant interception as Federico Valverde waited to pounce.
Antonio Rudiger meets the resulting corner but can't keep the header down.
Still goalless, but Union Berlin having to hang on at the moment
Real Madrid 0-0 Union Berlin
Frederik Ronnow leaps high to get fingertips to a Luka Modric piledriver, with the keeper spectacularly tipping it over the bar. Real are pushing and pushing.
Real Madrid 0-0 Union Berlin
Time for changes.
Two for both sides. Toni Kroos and Federico Valverde on for Real Madrid, with Lucas Vazquez and Aurelien Tchoiameni off.
For Union Berlin, Kevin Volland and Brenden Aaronson, on loan from Leeds, replace Kevin Behrens and Aissa Laidouni.
Galatasaray 0-2 Copenhagen
Three points look to be going home with Copenhagen.
A darting run forward from Birger Meling down the left flank was not covered defensively from Galatasaray.
Goalkeeper Fernando Muslera attempted to shut Meling down, but he finds Diogo Goncalves on the edge of the box and he neatly slides it into the bottom corner.
Real Madrid 0-0 Union Berlin
For the second time in this half, Real Madrid hit a post. It's a great save from Frederik Ronnow, diving to his right at full stretch, to push Joselu's header on to the post and away.
That's four headed chances Joselu has been unable to take, but a good effort that time.
Real Madrid 0-0 Union Berlin
A lovely pass with the outside of the boot from the magician Modric, but David Alaba just can't collect the ball when stretching.

Fantastic story regarding Union Berlin rise to the Bundesliga and their CL debut. Great seeing new faces in this competition and they're proving they're no pushovers against Madrid.

Real Madrid 0-0 Union Berlin
Real Madrid have started the second half superbly and are piling on the pressure. Joselu shoots at goal from Eduardo Camavinga's pull-back. Frederik Ronnow, a bit uncertainly, gets two hands to it and just about keeps it out.
Arsenal v PSV (20:00 BST)
David Raya continues in goal for Arsenal as they make their Champions League return.
The on-loan Brentford goalkeeper started ahead of Aaron Ramsdale in the 1-0 win against Everton at the weekend.
Leoandro Trossard, who scored the winner against the Toffees, also starts, while Gabriel Jesus and Kai Havertz also come in.
Arsenal XI: Raya, White, Saliba, Gabriel, Zinchenko, Odegaard, Rice, Havertz, Saka, Gabriel Jesus, Trossard.
Subs: Ramsdale, Smith Rowe, Nketiah, Kiwior, Cedric, Tomiyasu, Jorginho, Vieira, Nelson, Elneny, Hein.
PSV are led by former Newcastle loanee Luuk de Jong, while former Crystal Palace full-back Patrick van Aanholt is on the bench.
Armel Bella-Kotchap, who is on loan at PSV from Southampton, starts.
PSV XI: Benitez, Teze, Bella-Kotchap, Boscagli, Dest, Schouten, Veerman, Bakayoko, Saibari, Lang, de Jong.
Subs: Sambo, Ramalho, Tillman, Pepi, Drommel, Til, Waterman, Babadi, Lozano, van Aanholt, Vertessen.
Real Madrid 0-0 Union Berlin
Easily the best moment of the match. Rodrygo with the acrobatic scissor kick from Lucas Vazquez's cross, Rodrygo catches the ball sweetly but sees it bounce off the right post.
That was Rodrygo's second chance in 30 seconds as he had got free in the penalty area, the wrong side of his marker, but Frederik Ronnow stood up, made himself big and blocked the effort without knowing too much about it.
Real Madrid 0-0 Union Berlin
Rodrygo crosses from the right and Jude Bellingham has made a great run from deep, but just can't get on the end of the pass. He would've been in if the pass had been a bit better.

Madrid came from behind in most matches last year against elite teams. The absolute character of champions. They won’t be bothered by the first match!

Bayern Munich v Man Utd (20:00 BST)
It's no surprise, but Harry Kane starts for Bayern Munich.
There were doubts over Joshua Kimmich after he picked up a knock on Friday in the 2-2 draw with Bayer Leverkusen, but he is fit to start.
It means just the one change for the German champions, who drop Thomas Muller to the bench and start Jamal Musiala in his place at number 10.
Bayern Munich XI: Ulreich, Laimer, Upamecano, Kim, Davies, Kimmich, Goretzka, Sane, Musiala, Gnabry, Kane.
Subs: Peretz, Schmitt, De Ligt, Sarr, Mazraoui, Kratzig, Coman, Choupo-Moting, Muller, Tel.
Manchester United are missing 12 first-team players for this fixture. Mason Mount, Raphael Varane and Harry Maguire all trained on Tuesday but were subsequently omitted from the squad, with the first two having failed to fully demonstrate their fitness after injury and the latter picking up an unspecified knock.
It leaves Erik ten Hag with few options over selection. The United boss makes just the one change from the team beaten by Brighton at the weekend, with Facundo Pellistri replacing Scott McTominay, who drops to the bench.
Among the substitutes are 19-year-old Omari Forson and 18-year-old Daniel Gore, both of whom are midfielders, and three goalkeepers in Altay Bayindir, Tom Heaton and Radek Vítek.
Man Utd XI: Onana, Dalot, Lindelof, Martinez, Reguilon, Casemiro, Eriksen, Pellestri, Fernandes, Rashford, Hojlund.
Subs: Bayindir, Heaton, Vitek, Evans, McTominay, Gore, Mejbri, Forson, Martial, Garnacho
Real Madrid 0-0 Union Berlin
It was a pretty poor first half but we're back at the Bernabeu.
Arsenal v PSV Eindhoven (20:00 BST)
Arsenal striker Gabriel Jesus says the Gunners must believe they can win the Champions League.
Jesus is one of the most experienced players at Champions League level in the Gunners squad, having scored 20 goals in the competition for Manchester City.
"[The other day] some of them were joking in the gym and putting on the [Champions League] music," Jesus said.
"I think everyone is happy, the club, the players, the fans because it's a long time since we played in this competition. Now Arsenal are back.
"A club like Arsenal cannot stay without playing this competition.
"I think everyone here is experienced in how to control emotions. Some of them it's their first time playing the Champions League. It's a different competition but I still think everyone will do good."
