As Wales recover from a scrappy and injury-hit win against Italy, the make-up of their back row is a big talking point, with the likes of Justin Tipuric breathing down the necks of first-choice players Sam Warburton, Dan Lydiate and Taulupe Faletau.

In his 2015 Rugby World Cup column for the BBC Scrum V website, former Wales captain Colin Charvis names his favoured back-row combination, and suggests how head coach Warren Gatland could deal with the injury crisis presented by full-back Leigh Halfpenny and scrum-half Rhys Webb.

I believe Dan Lydiate, Sam Warburton and Taulupe Faletau is our strongest back-row.

It's got a good balance - and I'm not saying this as some sword of Damocles hanging over their head - you know when you need to see British Lion standard performances from your players.

Warburton, Lydiate and Faletau all have it in them to perform to that level - we just need to see it.

Justin Tipuric is right on the fringes of things and he has played well - you're not going to take that away from him.

But I just think the others when they're on form, they carry a bit more bulk and are defensively a bit more powerful.

And the pattern of play that coach Warren Gatland and his assistant Robert Howley and Shaun Edwards want means those three slot in so well.

Add Alun Wyn Jones around the park and probably Luke [Charteris] with his work-rate, and again, there's more bulk.

It's as if you're going into a street fight - you take the biggest bats you can and those five are five of the biggest bats in the street-fighting of world rugby.

And when we see them click, they are incredible.

They dominate the ruck area, they carry the ball, they defend.

Add to that people like prop Gethin Jenkins and hooker Ken Owens - I'm unsure about tight-head prop - but we have the makings of a very, very good pack.

Moriarty deserves a call-up

The injuries Wales suffered against Italy to Leigh Halfpenny and Rhys Webb mean Wales are likely to be forced to rejig their plans.

Traditionalists probably want to see a utility back coming in, a goal-kicker and we all know about Gatland's loyalty to players.

But the injuries could present an opportunity to bring back-rower Ross Moriarty in.

For a bit too long we've relied on someone like George North to do the bulk of the storming around and Wales are not obliged to bring in a like-for-like replacement for any injured player.

They could bring in a forward because they looked as if they needed a bit of bolstering.

They've got Liam Williams to come back from injury in the backs and Halfpenny could well end up being on the back-burner a little bit.

He could be out for four weeks, then return two weeks into the tournament.

But Ross has come so far in a short period and you need someone on the bench who can cover two positions at least. And he can do that.

Highlights: Wales 23-19 Italy

Nightmares, dreams and bogey games

You can read that we're moving up the world rankings and that we're doing quite well.

But when you're going into a tournament like the World Cup a lot of it is about confidence and consistency.

And the three warm-up games haven't shown confidence and consistency.

The 35-21 defeat in Cardiff by Ireland was a nightmare, the 16-10 win against them in Dublin was a wonderful dream and then there was a bit of a bogey game, winning 23-19 against Italy.

Reasons to be cheerful

Centre Scott Williams played very well against Italy and we've still got a few more players to see, a few coming back from injury, but confidence and consistency - we haven't got any more time to work on that.

We all know Liam Williams and Scott Williams, but we've never really seen them shine internationally.

The emphasis has been on backs North, Halfpenny, Jamie and Jonathan Davies etc.

But centre Jonathan Davies isn't there and the scoring pass Scott put through on the weekend was outstanding.

Liam's done some amazing things for Scarlets and some good things playing for Wales, but these guys - put them in a team that is a full hit-out, strong Welsh team and I think they'll slot in very, very well.

Wales were totally focused in the Six Nations apart from the second-half of that 21-16 loss to England.

They did that again when they won against Ireland recently.

And when they play like that, it's phenomenal what they can achieve.
