Sale's Ross Harrison is penalised at the scrum and Worcester are given the penalty just in front of halfway.

Ryan Mills steps up for another huge kick and connects sweetly to send it through the posts. Two superb kicks from the youngster so far.

Just before that, Worcester's Nick Schonert limped off and was replaced by Joe Rees.

Just five points in it at the break with a game threatening to break out at Kingsholm.

An obsession from both sides in kicking for territory is spoiling this a contest though.

So Sarries lead by five at the break, although I reckon the home side have probably shaded possession and territory.

James Hook's last-gasp penalty won it for Gloucester in this fixture last season - what odds on some similar drama tonight?

Yes, yes there will be a late sting in the tail.

Gloucester are penalised for failing to roll away and centre Owen Farrell lands a three-pointer from a fair way out.

Worcester are penalised for not rolling away and up steps the Sale try-scorer Danny Cipriani.

But the England man can't find the target as the ball sails wide of the left post.

Two from two missed so far.

A couple of minutes to go until the break, Saracens scrum on halfway.

Any late sting in the tail of this first half?

The hosts continue to chip away at Saracens' lead as Billy Twelvetrees lands another penalty, this time from around 40 metres, to give us a two-point game at Kingsholm.

Just as I said Worcester are struggling to get into the game they put some points on the board.

Sharks concede a penalty at the scrum and Ryan Mills decides to go for the posts from around 50 metres out.

The 23-year-old makes it look easy though and slots it through the middle. Fantastic kick from the fly-half.

Here comes big Ben - Gloucester number eight Morgan is on the charge, making himself a good 10 metres inside his own half.

He was busy defending his fitness earlier this week - and it was, of course, this very fixture in which he broke his leg last season.

Sale have won the last six games against Worcester and Warriors won't take too much heart from their start here.

It's been all Sale so far, as the visitors struggle to get out of their own half.

Still only 15 minutes on the clock though, so still plenty of time for things to change.

The Cherry and Whites do have some reward now though, as their pack this time draw a penalty at the scrum and captain fantastic Billy Twelvetrees splits the posts from a slight angle.

Around 12 minutes to go until half-time.

The natives don't sound too happy at Kingsholm, as Ben Morgan sneaks over behind a driving maul - but the referee's whistle had already gone, he'd already asked Gloucester to use the ball after the shove had been halted.

After Chris Ashton sends a cheeky wee grubber through Gloucester full-back Charlie Sharples is forced to dot the ball down behind his own line, which means Sarries have a five-metre scrum.

They win another penalty at the set-piece too - and this time Charlie Hodgson's radar is just about right as he kicks Saracens into an eight-point lead.

The clock has been stopped on 17 minutes at Kingsholm as the two packs take a brief breather before getting down to business.

Richard Wigglesworth inserts at last, and it's a decent old nudge from Sarries too - who recycle the ball and move up field.

Sale fly-half Danny Cipriani gets us under way in Greater Manchester.

Can Worcester make it two wins from two, or will Sale bounce back after last week's big defeat at Saracens?
