England scrum under pressure. Billy Vunipola picks and goes. But Scotland flood the breakdown and Joe Launchbury is pinged for hanging on.

Penalty Scotland and it is pretty much a gimme.

Tommy Seymour in off his wing and sniffing space on a lovely inside line.

The Scotland wing makes a half break, but is hauled down by a recovering Jonathan Joseph and spills forward.

Messy. Like the whole half.

England with the put-in in their own 22 metre.

"Frantic, frenetic stuff at Murrayfield, less the cagey opening moves in a dependably stodgy old tournament than the wild-eyed chaos of the last 10 minutes of the final game of the Championship."

"The key difference at the moment is in the breakdown. This is where Scotland are winning. At their breakdowns, they're getting the ball out within a second. England take the ball in and it sticks, so it's difficult for them to keep the momentum."

Billy Vunipola is a real copper-bottomed number eight. He slams into the blue wall and makes yards with his low body position. 

But the ball is back in Scotland hands with John Hardie pilfering.

England's Jonathan Joseph straps on his dancing shoes and almost finds a route around opposite number Mark Bennett.

Hauled down.

Turnover.

Still mostly merry chaos out there.

Daryl Guard: Mike Brown is a great ball-carrier, but sometimes I wish he would use his head and pass instead of running into traffic.

AK: Different coach, same old England. Absolutely awful discipline.

Stoney: New coach, same World Cup failures, giving away the same silly penalties. Same old rubbish.

"It's frantic. England are going to play any ball they can get their hands on."

Gavin Hastings

"It's as if England have been encouraged to throw the ball around. There's a time and a place for that, and it's not necessarily in the opening 25 minutes of your Six Nations campaign away from home."

Greig Laidlaw snatches at his kick and hooks it off the tee and wide.

Scotland with their tails up.

Wing Tommy Seymour smears George Ford across the Murrayfield turf as the England fly-half takes a high ball just outside his 22 metre.

Ford hangs on and John Lacey doesn't. Peep!

Penalty. 

A bit of genuine quality from Scotland as Stuart Hogg takes to the skies and claims a high ball before Finn Russell exposes space behind Jonathan Joseph with a precise kick for touch.

England penned back within their own 22 metre.

Still plenty of sound and fury, but not a lot of clarity and coherence to either side's play so far.

Dylan Hartley proves the point as the England captain misses his man with a bulleted line-out dart.

Scotland's Stuart Hogg is as slippery and buzzy as an electric eel.

The full-back gets himself out of a bit of bother deep in his own 22m with a neat dummy and step.

If there was any doubt about who has been on top, here are the possession stats so far. Plenty of ball for England.

"Scotland have been much better over the last five minutes. They do need to cut out the unforced errors, though."

Both teams are testing referee John Lacey's eyesight, judgement and patience.

England get the better of that little exchange, earning a penalty to relieve the pressure after good work from Billy Vunipola.

Jonny Duchezeau: I wonder if we will see the day England will score and then not concede a penalty straight away after

Mark Wilkins: Why is it that as a proud Englishman, I can't resist belting out "The Flower of Scotland", come Calcutta Cup time?

Ricciardo: Jack Nowell is having a great performance so far.
