A searing break through the middle of the pitch from Saints lock Alex Coles who bashes his way through Harvey Skinner's tackle.

Exeter are scrambling but do so well and Immanuel Feyi-Waboso leaps out of the line to almost secure the interception - a genuine attempt - but knocks on so Saints will restart with a scrum about 15 metres out from the Chiefs line.

You just sense with Chiefs with their brilliant fitness levels, the longer the game goes and it's tight, the more chance they have.

It's not been the flow we expected.

You've got to take the game to your opponent, it can't be 60 minutes then you decide to play.

This will go to the 80th minute I think, it's not gone how I thought it would.

Exeter's players are over the line - but the ball isn't.

They secure the line-out on this occasion and get going with the drive but it's a little messy and with bodies everywhere they come up short.

The referee says he did see it in real time and felt it was a coming together with the players in the same space rather than a deliberate tackle by Ethan Roots.

And having watched again he sticks with his original decision so Chiefs keep the ball and have an attacking platform.

A first TMO intervention now.

Not too much in it on first viewing.

I expect that now Saints have had this water break and they've had a minute to connect together - I expect them to start to click and tidy up a little bit after their soft errors.

Never mind the players that need a break, I think many of those watching here at Twickenham need one as well to catch their breath!

What an action-packed first 20 minutes - it's had everything.

A scrum penalty for Saints at the resumption but the high fives quickly turn to disappointment as they miss touch with the kick to give Chiefs possession.

The players and officials are sufficiently hydrated so away we go again.

Alex Mitchell has made more mistakes in the few minutes that he's been out than probably the rest of the season.

Two minutes later than scheduled we have the first water break of the match.

Plenty of water break chat at the football World Cup at the moment and it is greeted with a similar negative reaction here!

Let's not open that can of worms right now.

Exeter have a good attacking platform now.

Joseph Dweba can't find his jumper cleanly from the five-metre line-out though and Saints can clear.

It's pretty chaotic, all-action stuff out there.

Just what we want really!

I'm trying to work out why Exeter are getting so much change out of Northampton.

Those passes they usually play so fast are not quite coming off, they're not as connected.

Exeter have been doing their homework.

That looked for all the world like being Saints' second try!

Fin Smith's probing kicks are causing problems and this one is collected by George Hendy on the wing - he sends it inside to the unmarked George Furbank who spills it with the line at his mercy!

It wasn't a perfect pass but it's one you expect Furbank to take and the sort of try that Saints have been scoring all season.

A let off for Exeter for sure.

One enforced early sub apiece now as Saints scrum-half Archie McParland picks up an injury and that means Alex Mitchell joins the action.

A sub of the highest quality there joining the action a lot earlier than expected.

Both sides making errors but sides are really throwing everything they've got at this.

Saints have got to soak this pressure up. It's enormously fatiguing down there.

I don't feel any panic from either side. We've kind of given Exeter that little bit of confidence back, but it's actually been two scores and two mistakes from either side and I think that is pretty much down to the pressure that's on down there.

Saints are being forced to scramble in defence to keep Exeter out.

Henry Slade is close to going over and then Campbell Ridl is stopped about five metres out shortly afterwards.

It was a great start by Saints but Exeter have come roaring back into it - as they did against Bath last week.

Suddenly it's all Exeter!
