Still only Tommaso Allan's penalty divides the two teams. But Scotland win a kickable penalty with the Italians off their feet at the ruck.

Italy captain Sergio Parisse is almost clean through but is brought crashing down. The play switches to the other end and Scotland look to take advantage from a scrum deep inside the Italy 22.

Scotland need to respond. A monster boot from full-back Stuart Hogg takes them into the Italian half.

David Golding: How come top international pitches carve up very badly yet the local rugby clubs pitches are fine and don't get ruined so quickly?#bbcrugby

Danny Till: Really rate Gori at 9 for Italy. Starting to come on now, does the basics very well #bbcrugby #rugbyunited #rugby #sixnations

"That was a very confident kick and we know Tommaso Allan is very much a confidence player. When he is on a roll he gets better and he will take a lot of confidence from that kick."

Scotland concede a penalty under intense Italian pressure in their own 22. The referee plays advantage but it comes to nothing and he goes back to the original award. Fly-half Tommaso Allan, whose uncle John won nine caps for Scotland, sends the kick over. Italy have their noses in front.

Scotland concede their third scrum penalty, with tight-head prop Moray Low the culprit each time. Risking the wrath of referee Steve Walsh - and a potential yellow card - if that trend continues.

A Scotland kick is charged down and Sean Lamont tidies up. One or two sloppy exchanges by the visitors but they are beginning to put the hosts under pressure.

"Everything apart from the final kick [from Seymour] was really good. The line-out was good, they kept it simple and worked from there. A disappointing end but promising signs so far for Scotland."

Italy win a second penalty at the scrum; they kick it to touch but Scotland respond by stealing the Italian line-out for a second time.

Jim Hamilton steals an Italy line-out. There's a good Scotland attack, with Johnnie Beattie involved, and a superb floated pass by Duncan Weir finds Tommy Seymour in space on the right wing. But rather than cutting back inside off his touchline, Seymour kicks ahead over the try-line and the ball goes dead. Opportunity missed.

And we're off. Early scrum deep inside Italy territory but the hosts are handed an opportunity to clear their lines after the referee awards an early penalty against Scotland

The piercing sound of bagpipes echo around the Olympic Stadium. The national anthems are under way. We're almost ready.

And here they come. Greig Laidlaw leads Scotland into a wall of sound at the Olympic Stadium. Here's a reminder of the players who made the cut:

Italy: Luke McLean, Angelo Esposito, Michele Campagnaro, Gonzalo Garcia, Leonardo Sarto, Tommaso Allan, Edoardo Gori, Alberto De Marchi, Leonardo Ghiraldini, Martin Castrogiovanni, Quintin Geldenhuys, Joshua Furno, Alessandro Zanni, Robert Barbieri, Sergio Parisse,

Replacements: Davide Giazzon, Matias Aguero, Lorenzo Cittadini, Marco Bortolami, Paul Derbyshire, Tobias Botes, Luciano Orquera, Tommaso Iannone.

Scotland: Stuart Hogg, Tommy Seymour, Alex Dunbar, Matt Scott, Sean Lamont, Duncan Weir, Greig Laidlaw, Ryan Grant, Scott Lawson, Moray Low, Richie Gray, Jim Hamilton, Ryan Wilson, Chris Fusaro, John Beattie,

Replacements: Ross Ford, Alasdair Dickinson, Geoff Cross, Tim Swinson, David Denton, Chris Cusiter, Duncan Taylor, Max Evans.

So who should we look out for in the Italy side? Scotland have a familiar face appearing against them as former Scotland Under-20 fly-half Tommaso Allan starts for the Azzurri, representing the country of his Italian mother.

There are also record-breaking run-outs for skipper Sergio Parisse and prop Martin Castrogiovanni as they both earned their 104th caps, eclipsing the previous highest Italian tally set by Andrea Lo Cicero.

"You saw Wales' reaction to their game against France last night and we know there needs to be an outstanding performance by Scotland today. There's no better place to get a response."
