Scotland face Italy in their penultimate Six Nations match at the Stadio Olimpico in Rome on Saturday.

Duhan van der Merwe scored a hat-trick of tries as Scotland beat England two weeks ago to retain the Calcutta Cup.

The winger needs one try to match Stuart Hogg's Scotland record of 27.

His overall total of five tries from three games makes him the top scorer in this year's Championship.

Paolo Garbisi's last-gasp penalty miss a fortnight ago meant Italy were denied a first Six Nations victory away to France, with the Azzurri having to settle for a 13-13 draw.

The result was not enough to move them off the bottom of the Six Nations table but did halt a run of seven consecutive defeats in the championship.

Team news

Italy: There are three changes for the Azzurri, including a debut for wing Louis Lynagh, the son of Australia great Michael Lynagh.

His inclusion means Tommaso Menoncello moves back to centre, with Federico Mori dropping to the bench.

Flanker Sebastian Negri returns after missing two games through injury, replacing Riccardo Favretto, and prop Simone Ferrari comes in for Giosue Zilocchi, who is among the replacements.

Scotland: The visitors also makes three changes, including a first Six Nations start for George Horne, who comes in for first-choice scrum-half Ben White, who is rested.

Sione Tuipulotu will miss the rest of the tournament with a knee injury, so Cameron Redpath deputises at inside centre, while flanker Andy Christie earns his first Test start in place of Jamie Ritchie, who is a replacement.

Commentator's notes

Sara Orchard: Scotland are favourites and should have enough experience to stop this game being turned into a banana-skin fixture.

All the hype is about the wings. From a Scottish perspective, Duhan van der Merwe is now one try away from equalling Stuart Hogg's Scotland Test record. It's now 'when' not 'if' he will break it.

For the Italians, the headlines focus on Louis Lynagh. Come 14:15 GMT on Saturday he's officially Italian, having had three passports (England, Australia and Italy) to choose from. While Lynagh's inclusion has created waves, the return to action of hulking back-rower Sebastian Negri will calm and assure Italian fans.

View from both camps

Italy head coach Gonzalo Quesada on debutant Louis Lynagh: "He will be up against a great player [Scotland wing Van der Merwe] but he plays and defends well, he's a good communicator and we're staying true to our philosophy of giving young players their chance."

Scotland head coach Gregor Townsend: "In terms of performance, we're a little bit away from what we know we can deliver. The first 45 minutes against Wales is probably still the best we've played.

"We had elements of control throughout much of the France game and for the last 60 minutes of the England game. But there's still a lot more to come from us."
