Scotland head coach Gregor Townsend tells BBC Scotland: "It's been a week we probably never had before in terms of the amount of meetings, review meetings and honest conversations we've had as a group because it reflected what a disappointment it was in those last 20 minutes [against Argentina].

"It's been an invigorating process this week and I feel there's been a lot of coming together with the group and I feel we'll be a better team for the experience.

"When we're playing the Six Nations we know there might be other situations in which we have to adapt so the most important thing is how we connect on the field as a group.

"The door gets opened when we lose for people who want to criticise. My 100% commitment is on this team and how we get better and how we also build on what we've been doing really well.

"There's been lots of positives parts to our play we just need to make sure that we don't let those poor areas get into our game like what happened in Argentina.

"It's going to be a huge physical challenge [against Tonga]. I think the weather will suit them. We have to be patient but we have to be physical and show huge effort."

Flower of Scotland rings around Murrayfield as kick-off fast approaches.

It's another big crowd, despite the back-to-back defeats.

Captain Sione Tuipulotu has thrown his support behind Gregor Townsend, despite the below-par autumn results.

After an 85-0 drubbing of the USA, Scotland were edged out by New Zealand and denied an historic first win over the All Blacks, and then collapsed from 21-0 up against Argentina to lose 33-24.

"I don't think I've ever stood in front of you guys and not spoken honestly," Tuipulotu said. "My honest answer is, I'm fully behind my head coach, and so are all the players.

"I take a lot of accountability for what happened on the weekend [against Argentina]. I'm the captain of the team.

"Gregor is not down there playing rugby. He's put us in a position to get up 21 points and I take accountability as the captain for the reason that maybe we let that lead slide.

"We didn't execute against New Zealand. I think it's more of a players thing for me, because I'm down on the field, I'm out there being able to influence the situation along with all the other players.

"So I stand in front of you all here and speak honestly that I'm fully behind Gregor. I still believe he's the man for the job in what we can achieve leading into the World Cup."

I've been a fan of Gregor Townsend for a long time.

There are people out there who don't like him and play down his achievements. I don't do that, but I don't see this team progressing and I think it's time for a new voice.

There's no guarantee things would get better, but I think it's worth a try.

Tonga - ranked 19th in the world - were last competing in the Pacific Nations Cup in September.

They beat Canada to finish third after a heavy semi-final defeat by Japan.

Regardless of form, Scotland are expected to win - and win well - this afternoon.

Both games against New Zealand and Argentina were winnable.

The game was won last weekend, it's not arrogant to say that. I keep watching it back and it's simple things they can do to make it work.

They seem to have some real brain fades in the middle of games and lose composure.

It's been a tough couple of weeks as a supporter and I'm sure it has been for the players and staff too.

Head coach Gregor Townsend came in for criticism after last Sunday's 24-33 loss.

Scotland led by 21 points at one stage before collapsing in awful fashion.

It raised questions over the team's mentality and the general direction of the national team, with Townsend grilled on his future at a press conference earlier this week.

Zander Fagerson makes his first appearance in more than seven months, while captain Sione Tuipulotu is the only player to retain his place in Scotland's starting line-up.

Glasgow Warriors tighthead Fagerson has been sidelined since April through a combination of calf and knee injuries.

But he will be part of an experienced front row alongside fellow Warriors prop Rory Sutherland and Harlequins hooker George Turner, who will win his 50th cap, in Scotland's final autumn Test.

There is no place in the squad for Bath fly-half Finn Russell, joint record try-scoring wing Darcy Graham and full-back Blair Kinghorn as Gregor Townsend makes sweeping changes.

Joint record try scorer Duhan van der Merwe returns after being missing from the starting line-up for the past two Tests against New Zealand and the Pumas, with Kyle Rowe on the other wing.

Bristol Bears' Tom Jordan starts at full-back, while Saracens fly-half Fergus Burke will win his third cap in place of Russell.

In the back row, Edinburgh's Magnus Bradbury will make his first start for three-and-a-half years in the number eight jersey, while flankers Andy Onyeama-Christie and Jamie Ritchie are handed their first appearances of the autumn.

Scotland: Jordan, Rowe, Smith, Tuipulotu, Van der Merwe, Burke, White; Sutherland, Turner, Z. Fagerson, Samuel, Williamson, Onyeama-Christie, Ritchie, Bradbury.

Replacements: Ashman, McBeth, Hurd, Sykes, Bayliss, Horne, McDowall, Steyn.

Tonga: Fisi'ihoi, Maile, Tameifuna, Mataele, Poloniati, Paea, Moala, Inisi, Takulua, Pellegrini, Tapueluelu, Kata, Inisi, Filimone, Havili.

Replacements: Moli, F. Paea, Kite, Timani, Lokotui, Halo, Fainga'anuku, Tuitavuki.

Boos around Murrayfield are a rare old thing, but that's what met the full-time whistle last weekend as Scotland collapsed to a dismal defeat by Argentina.

They have the chance to finish what has been a disappointing autumn on a high this afternoon with Tonga visiting the Scottish capital.

Kick-off is 35 minutes away...
