Here comes that enforced change, then. Bukayo Saka is replaced by Eberechi Eze.

That doesn't look good. Bukayo Saka is waving at the bench after going down.

Eberechi Eze is getting ready to come on.

Bad news for Arsenal early doors. Bukayo Saka is sat on the pitch and looks like he is going to have to go off. His ankle looks to turn awkwardly as he made a pass.

Neither Curtis Jones nor John Stones are available for Inter Milan tonight.

But fellow England international Djed Spence makes his first start in the Champions League for the Italian side.

Second header on target from Nicolas Jackson. This time from a left-wing Emiliano Buendia cross. Again straight at the keeper.

John McGinn has moved level with Ollie Watkins for the most appearances made in major European competition for Aston Villa (37).

Aston Villa already dominating possession and that was a good chance for in-form Nicolas Jackson. You'd have expected him to score with that header there.

It's a really interesting game so far. Very cagey as you'd expect with the ball zipping about. It's interesting that the best attack that Arsenal had was with a long kick from David Raya.

It has been a pretty quiet opening few minutes but Arsenal have the first attack as Kai Havertz gets into the box and crosses from the right. Bukayo Saka tries to get a shot off but there's too many Bayern Munich players in the way.

Villa have their first chance in the opening four minutes. An inswinging cross from John McGinn finds Nicolas Jackson but his header is straight at Arild Ostbo.

Manchester United

Manchester United captain Bruno Fernandes speaking to TNT Sports: "It's not the first time, we started on the wrong foot, and they scored very early. Not much pressure on the ball, not many good movements with the ball, not many things going our way.

"Conceding early makes us go into game with a mood of defeat, it's difficult to get out of that, trying to be brave, to have the ball and make something happen. If we are not able to do that, it is going to be very difficult to get out of this situation.

"It's a decision from the staff to not press man to man and sometimes leave space behind and try to get the ball, wait for them, but sometimes when you give space to these teams they get confidence."

On whether he is saying Michael Carrick got his tactics wrong: "That's on the manager and staff to see, not me. Sometimes you have to be more brave under pressure, take the risk of pressing high and making them uncomfortable. As you saw with them [Como], the centre-back was coming to mark me in my own half. We need to do that as a team but we were unable to.

"A team that plays through the middle with small connections, if you give them too much time and space then they can hurt you out wide."

Can Villa make it three wins out of three in the Champions League?

They were so impressive in last week's 6-0 win over Fenerbahce I went straight in and signed two of their players into my Fantasy Premier League team.

A great noise inside the stadium in the first couple of minutes of this match.

The Bayern fans at either end of the ground were chanting at each other.

The Arsenal fans are high up behind David Raya's goal and making a decent noise too.

The late games are under way.

Manchester United

Manchester United midfielder Youri Tielemans: "It was a very bad match from us. The fans come out here and we put out a non-performance like this, it's not good enough from us."

Madueke is very, very different to what Eze provides and for me it's just a matter of what you want.

For me, Eze isn't the type of player who hugs the touchline, stays out wide, and enjoys driving at full-backs trying to commit them.

I think he wants to play and be clever with his movements, stepping inside the pitch, so it doesn't surprise me that Madueke is in the team because he will provide that width, he'll stretch the pitch, and make life difficult for the full-back.

Jose Mourinho has started Fede Valverde at right-back again... he has two natural right-backs in the squad in Dumfries and Trent Alexander-Arnold. Neither starts. Shows who his trust lies with.

When I look at the two teams, the midfield battle, Arsenal definitely look the stronger of the two teams. I think the legs in there, are what they're really going to try to over-run them and be more physical than Bayern.

The champions of Germany and England meet in an eagerly anticipated fixture which, but for Bayern's Munich semi-final defeat by Paris St-Germain, would have been last season's final.

The hosts' expansive, high-risk approach contrasts with Arsenal's more measured and disciplined style.

The Bavarians, unbeaten at home in the group stage or league phase of European competition for 13 years, have scored 23 goals in their four home games this season.

However, they have kept just three clean sheets in 10 matches this term and conceded three times in last week's draw with Viking, a result boss Vincent Kompany blamed on individual mistakes.

Bayern will need to be almost error-free against an Arsenal side with a similarly outstanding record at this stage.

The Gunners have won 14 consecutive Champions League games in the opening phase of the competition, including a 3-1 victory when the sides met at the Emirates last November.

Harry Kane drew a blank that night, but the former Tottenham star has an excellent record against his old north London rivals and is looking to score in a 10th consecutive Champions League game.
