Our 5 live colleageus estimate that there are about 50,000 inside Old Trafford tonight.

And away we go at Old Trafford, and at West Brom v Manchester City too...

Conor has sketched that with charcoal, you know. No end to the man's talents.

Vicki Sparks and Steve Claridge are currently commentating on 5 Live Sports Extra at The Emirates.

Nothing much to report from the opening 10 minutes at Goodison Park.

But we like this stat. The Moyes effect!

A lot of these Burton players will never get a chance to play at Old Trafford again.

They are coming here knowing however many changes Manchester United make, they'll still be unbelievably strong. Will Burton win the Carabao Cup? No.

The manager is probably thinking 'do my players need an extra game?'. However, those Burton players who have been rested are missing out on the one opportunity to play against a Jose Mourinho side at Old Trafford.

A magnificent effort from Giroud. It was at shoulder height, he hit it with a magnificent volley, really unlucky, it was a lovely ball in and a lovely passage of play from Arsenal.

They look hungry and have started just as Arsene Wenger would have wanted.

Brilliant effort! What a fine strike that is as Olivier Giroud throws himself into a scissor kick, left-footed, and against the top of the bar!

Superb technique. And very unlucky.

Willy Caballero has made his first save in a Chelsea shirt, down low to stop an effort from Andreas Bouchalakis.

• United have been eliminated from the League Cup in two of the past three games played at Old Trafford against lower-league opponents - most recently losing out in a penalty shootout to Middlesbrough in October 2015.

Manchester United manager Jose Mourinho on Sky Sports: "It will be nice to be in the next draw but my experience in the English cup says every match is tricky, every opponent has a dream.

"Let's go step by step. It is an option to play with the majority of the players who haven't played so far."

Dan Graham‏: Burton Albion are resting several players, against Man Utd, that's why this cup doesn't mean anything anymore.

Andy Kershaw: Hoping for an upset or two tonight, but I can't see where they could come from. Goodison and The Hawthorns maybe?

Vernon Lord: Thoughts on Luke Shaw... overweight, rapidly becoming undelivered promise, time to cut our losses?

Straight from the kick-off, Rodney Kongolo tests David Ospina for Donny, before Theo Walcott goes close at the other end.

And we are under way at Arsenal, Chelsea and Everton...

This is a decent opportunity for Arsenal's players to sharpen up as much as they can. It is a game of football they will try to enjoy.

BBC Sport revisits the 2006 FA Cup tie between Burton Albion and Manchester United, before the two clubs meet again in the Carabao Cup on Wednesday.

Listen to live coverage of Manchester United v Burton Albion, 20:00 BST on BBC Radio 5 live and the BBC Sport website & app.

• Burton Albion are at the third-round stage for just the third time in their history, losing to teams in the second and fourth tiers on those occasions.
• They have faced Premier League opposition on three occasions in the League Cup, with the Brewers being eliminated twice and progressing past QPR in August 2014.
