Stephen Myler makes no mistake from 15 metres out and almost right in front of the posts to maintain his 100% record. Northampton are in front for the first time.

The Northampton pack rumble on after Courtney Lawes takes the line-out and Sarries are penalised for the third time in three minutes, handing Stephen Myler a relatively simple kick for goal.

Saracens are penalised again, this time at scrum-time near halfway. Stephen Myler kicks deep and Saints will have a line-out on the Saracens 22.

Saracens fly-half Owen Farrell gets us back under way but the visitors are immediately penalised, giving Northampton the chance to kick for field position.

The sides re-emerge and Northampton have had to make another change, with Tom Stephenson replacing James Wilson. Ken Pisi will go to full-back.

But will extra-time be needed? Or can we find a winner after 80 minutes and, if yes, who's your money on?

You might remember that last year's Premiership final between these sides went to extra-time and given we're level here it might be worth a reminder of what would happen if we finish all square.

Firstly, we would have 20 minutes of extra-time, 10 minutes each way. And if the sides still cannot be separated then the team that has scored the most tries will go to Twickenham.

If they're level on tries too then it'll be down to penalty kicks. Surely it won't go that far, will it?

"Saints will be disappointed to only be level after dominating the opening half. But they were left chasing the game when Saracens wing David Strettle hacked on for Duncan Taylor, exploiting a gap behind the defence that was left by the stricken Ahsee Tuala.

"So far, the visitors have shown little in attack - but, they do have Owen Farrell's boot. You feel Sarries must show more after the break though, or the champions seem likely to eventually grind them down."

So, here's the tale of the tape at the break.

That is indeed the last kick of the half and both sides troop off to the dressing rooms. This is too close to call.

The kick is right in front of the posts, 20 metres out, and Stephen Myler slots it over with the minimum of fuss. We're all level going into half-time.

Northampton try to get moving but to their credit Saracens stand firm. Saints are up to eight, nine phases but they can't get over the 22. That's a dozen phases now. Ken Pisi then gets absolutely smashed by Jacques Burger who is then penalised for not rolling away. Burger reacts angrily and shoves Lee Dickson in the chest, but there is no card and it will just be a penalty with the last kick of the half.

We're a minute away from the break but Northampton have a penalty just inside their own half for Jacques Burger rolling Luther Burrell by the neck. Stephen Myler kicks deep and the Northampton pack will have one last chance for a catch and drive to the line.

Worryingly for Northampton, James Wilson, who replaced Ahsee Tuala at full-back early on, also appears to be struggling with an injury. Saints might be keen for half-time to come now. They've lost that momentum they had earlier in the half.

This time Owen Farrell makes no mistake as he strokes over his kick from a slight angle 40m out to give Saracens the lead for the third time.

No sooner has that kick gone over then Alex Waller, who scored the try that won the title for Saints last season, replaces Alex Corbisiero at prop.

But it's not long before Saracens are awarded a third penalty in quick succession midway inside the Northampton half after Saints are penalised for not rolling away.

This one's more difficult for Owen Farrell and this time he pulls his angled kick across the face of the posts and wide.

That's now three penalties in only a matter of moments as new England squad call-up Maro Itoje draws the penalty for Saracens, prompting Owen Farrell to call for the tee once again.

And it's no surprise that Stephen Myler makes no mistake with the boot from right in front of the posts. We're all square once again.

But how often do you see one side score a penalty and then concede one? That's what Saracens do here as Petrus Du Plessis tackles George Pisi off the ball. Stephen Myler has a chance to tie the scores once again.
