Have Exeter got a response to that or is going to be heartbreak for the Chiefs yet again?

Every Exeter penalty, every scrum they win and every line-out they take is being cheered like a try here.

Exeter's fans are desperate to wipe out the bad memories of Twickenham 12 months ago, and they're getting closer and closer to that hope becoming reality.

Another big victory for Exeter as they surge forward on Saracens on the edge of their 22 after kicking the high ball to Mike Ellery.

Marcelo Bosch can't find a way out when he receives the ball and skews a clearance out only some 10 metres forward.

How big a missed chance is that for Saracens?

Gareth Steenson again boots it clear from the penalty to ease the pressure on the hosts.

Superb break from Saracens out of their own 22 as Duncan Taylor won the ball in the air initially.

Mike Ellery can't quite find the space or pace to get in around the back of the Exeter defence as he gets the ball on the right wing.

Saracens spurn the chance to finish off as they concede a penalty on the floor for not releasing when they were 10 metres short at the breakdown.

Saracens fans are in good voice at Sandy Park.

They know one kick, one piece of magic can win this semi-final for their side.

Couple of changes for Exeter see Thomas Waldrom and Phil Dollman go off.

Sam Simmonds and Henry Slade come on as we move towards the closing stages still no closer to knowing who's heading for Twickenham and who's campaign will be over come full-time.

Great break for Saracens and Schalk Brits deep into the Exeter half.

The kick into the Exeter in-goal area then comes from Duncan Taylor's boot but it's too far ahead of the chasing Alex Goode to win the race to touch it down.

Gareth Steenson's turn to make mistake with his boot and kick out on the full as Exeter look to threaten in the Saracens half.

A few nerves perhaps starting to creep in to both sides' games.

More indiscipline from Saracens at the breakdown concedes another penalty on halfway and Gareth Steenson can put it into touch inside the visitors' 22.

This is a crucial time for Chiefs to somehow get possession and somehow get that ball back in the Saracens' 22.

Three changes for Exeter in the front row in response to conceding that try.

Here we go into the final quarter of this one (extra time permitting of course!).

Owen Farrell fails to find touch with a penalty after Saracens get a chance on halfway.

James Short kept it from going out, but Saracens have the ball back in their hands.

Change at scrum-half for Exeter as Will Chudley replaces Stuart Townsend.

Saracens need a change in momentum here to claw back into this one. Exeter need some cool heads to close it out and guarantee their place at Twickenham next Saturday.

Mako Vunipola back on the pitch after that clash of heads with Dave Dennis and back in the thick of the action for Saracens.

Exeter again build the phases but eventually they see it turned over ad Vunipola pounced on the Saracens side on the floor to force the error.

Chance for the defending champions to breath a bit and clear the ball up field.
