Former Bath, England & Lions centre

I've seen the future, and he wears a green and black shirt.

Hartley made a massive impact for Northampton against Worcester

His try showed us what he's all about. He smashed through one defender, and then bounced off another to score a magnificent try.

For me, he's a shoo-in at hooker for England. It was the most dynamic performance from an English forward I've seen in some time, a massive injection of tenacity and power.

You get something similar from James Haskell and Tom Rees and it's just infectious for the rest of the team. Martin Johnson will want players like that.

I was very impressed with Northampton in general on their return to the Premiership. They played with tempo, ambition and really got stuck in to Worcester, and Hartley personified that.

The Saints also have Jon Clarke at centre who is a very good player. England have been lacking a try-scoring centre since Will Greenwood retired and Clarke could just fit the bill.

As for Worcester, I wouldn't be too worried if I were them, they have improved on last year already. I certainly don't see them fighting a relegation battle - that will be between Bristol and Newcastle.

Gloucester might have progressed, but I didn't see much sign of that at Kingsholm on Sunday.

I had big hopes for them after last season. I thought they would really come out and show that they meant business.

They had enough firepower to really take it to Leicester but they just didn't do it. They spluttered badly throughout.

Actually, coughed would be more accurate, because they coughed up the ball in dangerous situations time after time.

Luke Narraway's failure to put away what could have been a crucial try was the rugby equivalent of missing an open goal from five inches out.

Narraway's error proved to be costly for Gloucester

He must have struggled to look his team-mates in the eye afterwards. It was just a severe case of white-line fever as he slipped up - there's not really an excuse for it at this level.

Leicester will always hang in there and they won through not making as many mistakes.

I appreciate it was the start of the season but what was especially disappointing for me was the fact that it wasn't the new laws that messed Gloucester and Leicester up, it was the old ones being refereed properly.

Players went off their feet at the breakdown and, quite rightly, the referee pinged them for it. All in all, it didn't live up to the billing. On that showing, Leicester and Gloucester don't look anything like title favourites.

Why Gloucester can't do it in big matches is something of a mystery to me, and I'd genuinely like to hear what the Shed heads think about it.

As for Wasps, they may have lost but you write them off at your peril. They've got too many quality players not to be there or thereabouts.

When they play at their best they are pretty much unstoppable and only a side with their quality can play at that level. If they can recapture that quickly, they'll be fine.

Jeremy will also try to take time each week to answer questions from users, and here are a selection of the opening batch:

What impact do you think the ELVs had over the first weekend?
Cowshot

I didn't see that many problems, for me the teams had more trouble with the old laws than the news ones.

But there was not a great conversion rate of opportunities from 5m scrums. As I said last week, attacking teams should be scoring with at least 80% of the opportunities they get from a 5m scrum because there's so much space.

It's perfect for a dynamic back-rower to pick and go, set up a quick ruck and the next phase should be almost walking over. If the attacking team don't score, they have made an error.

What will coach Ian McGeechan bring to the Lions tour that was missing in New Zealand?
incababy

Geech will take it back to basics and return to the true tradition of what the Lions are.

Every player who goes on that tour knows they have a chance to prove themselves and get selected for the Test team. That simply didn't happen in New Zealand. Sir Clive Woodward had far too many pre-determined ideas, and that doesn't work on a Lions tour.

The Lions is about opportunity; the world is your oyster once you get out there and start performing.

With his Lions history as player and coach, Geech knows everything there is to know about what the whole concept is all about.

Who do you fancy for this year's Heineken Cup?
Collymore4England

I went for the Ospreys last year and they let me down but I'll go for them again - assuming they can get their scrum-half Mike Phillips back in a reasonable amount of time.

The only thing missing from the Ospreys last year was a mental hardness. They have so much talent and are almost a Test side - it's about time they won major honours but their time has to come very soon.

Do you think Shane Geraghty will get a chance to shine at centre with Martin Johnson in charge of England?
Intl Wookie Hunter

Shane is a very talented player but it's more potential than achievement so far.

I don't think he will get too many opportunities so any time he does get a chance he has to absolutely nail it.

He's not the biggest man and for players like him missed tackles will be put down to that - but it shouldn't be. It comes down to technique.

I expect a fully-fit Danny Cipriani to be an automatic choice at fly-half so can Geraghty play inside centre? Attack-wise, there's no question. He's got great hands, real pace and everything you need. But there's more to it than that.

What is your honest opinion on the Guinness Premiership? I find it very low on skills and far too forward orientated.
IANTO382

In my honest opinion, the skill level in the Premiership is poor.

Some people might call defence a skill, but I'd describe it as a basic requirement. It should be a given that you can tackle and line up in the right place.

But to attack takes ingenuity, ambition, skill and precision. You only have to look at England's games over the last few years. Since Jason Robinson retired, how many players in that England back-line can you say 'aren't they full of skill?' about?

Cipriani, yes. David Strettle, as a runner, maybe, but who else? When was the last time you saw the ball whizz down the England line with every player hitting it at pace? It's been sadly lacking.

But I don't think it's ingrained. Maybe it's wishful thinking but there are players with talent out there. They just have to get the ball in their hands.
