Lovely football again from Arsenal. Alexis Sanchez drives at the defence, finds Mesut Ozil to his right, the German's shot is low and hard but Manuel Neuer extends his wrist to push it out. What a great save, and Theo Walcott can't connect. Very promising start from the hosts.

"The protesting Bayern fans are now filing in late as planned - to very warm applause from Arsenal fans all around The Emirates. As protests go, very effective."

Worth noting that when the Bayern fans made their way to their seats after five minutes, they were widely applauded by supporters inside the ground.

Strong start from Chelsea with Willian looking a threat down the right flank. Cesc Fabregas has his first shot of the night, low and easy for the keeper. 

The goals are already coming in the Football League - follow all the action here.

Lovely football! Santi Cazorla dissects the Bayern backline with a peach of a pass, right into the run of Hector Bellerin. Bellerin serves up a tap-in for Theo Walcott but the offside flag is raised. Great football. 

Neymar is wearing gloves, Luis Suarez is clasping his hands together before kick off and blowing on them furiously. Barcelona have never played at BATE Borisov's new stadium. They now know it's cold.

Barca have a win and a draw so far in their defence of the Champions League.

Under way in Ukraine too, where the temperature looks a lot colder than north London.

"A large number of Bayern Munich fans are planning a late entrance tonight after about five minutes in protest at being asked £64 for a match ticket. And those inside have made their own feelings known."

Twenty seconds! That's how long it takes Robert Lewandowski to skin Per Mertesacker and scuff a shot wide from 15 yards out. Goodness me!

The Arsenal get us under way...

Hundrers of Bayern fans are missing the first five minutes tonight as they protest against the £64 ticket prices.

Those who have made it in hold up a banner which reads 'football is not worth a penny without fans.'

That is the biggest tunnel I've ever seen! You could play the whole game in the the tunnel. Anyway, here we go...

Per Mertesacker holds court at the front of the teams in the tunnel, sharing a joke or two with his compatriots. You didn't get this from Gary Neville.

Here they come!

Only Cristiano Ronaldo (44 goals) and Lionel Messi (26) have scored more goals in the Champions League than Robert Lewandowski (25) since 2012-13.

"New hair don't care," writes Samir Nasri.
