England's Maro Itoje is back in the Saracens line-up after the autumn internationals and captains the hosts against Bulls.

He is one of five changes to the side beaten by Newcastle eight days ago.

Plenty of international pedigree in the Bulls' starting XV too - a big test awaits.

Saracens: Daly; Elliott, Cinti Luna, Tompkins, Segun; Burke, Van Zyl; Carre, George, Riccioni, Itoje (capt), Isiekwe, McFarland, Gonzalez Samso, Willis.

Replacements: Dan, Mawi, Clarey, Wilson, Earl, Simpson, Eden, Parton.

Bulls: Le Roux, De Klerk, Moodie, Kriel, Williams; Goosen, Papier; Steenekamp, Grobbelaar (capt), Klopper, Vermaak, Van Heerden, Van Staden, Wiese, Hanekom.

Replacements: Van der Merwe, Tshakweni, Smith, Kirsten, Coetzee, Johannes, Dyantyi, Vorster.

Referee: Craig Evans (Wales)

The games come thick and fast on this Champions Cup Saturday - two more contests, both in Pool Three, get under way at 17:30 GMT.

Saracens host South African side Bulls, while Munster are at home to French club Stade Francais.

We'll have updates of both games shortly.

Player of the match Juarno Augustus, speaking to Premier Sports after scoring two tries for Northampton: "I was there at the right time in the right position to score those tries. It's a good result for us.

"We prepared for these conditions and we tried to play the game tighter and run the ball.

"Last year we did quite well but this year we want to take an extra step."

On teenage team-mate Henry Pollock: "That guy has a bright future. He's unreal. He was up there to get man of the match. If it was my pick, I would have given it to him."

It's Bulls away next up in seven days' time for Northampton, who have made the perfect start to their Champions Cup campaign.

Six tries and a maximum five points for Northampton Saints.

Henry Pollock's inclusion in the starting XV was one of the headlines before this match and the 19-year-old's late try put the icing on a cake that has got very soggy and windswept thanks to Storm Darragh.

Northampton are seeking more points in the closing seconds, but hold up - there's a bit of a melee during a break in play between the two sets of players.

Nothing much to it though and we play on. Only a couple of minutes away from a hot shower or bath.

Archie McParland's kick down the line somehow stays in play and Castres can only concede a line-out about seven metres from their try line.

A chance for a final flourish for Northampton?

After a defeat for Bath on Friday and Exeter's loss earlier today, we're about to see a first win for an English club in this season's Champions Cup.

Goodness me, a comedy of errors!

Although it's not surprising at all, given the conditions, that nobody from either side can gather the slippery ball cleanly after Northampton's Archie McParland failed to cleanly gather a kick through near his own try line.

Castres will have a scrum five metres from Northampton's line.

Now it's Northampton's turn to be held up over the line.

Juarno Augustus was the man denied by a couple of white shirts near the posts.

Saints do have a penalty five metres out though...

It's tapped and three Castres players charge together for the line, but Northampton hold the ball up over the whitewash and the home side survive.

You would think Northampton have the victory pretty much in the bag in this position, but Castres are looking for a way back.

From a line-out, they nudge towards the Saints' line with a few pick-and-goes, then spread it wide but are held up.

We'll come back for an earlier penalty.

And Northampton think they might be over, but we're checking with the TMO to see if Curtis Langdon's effort will count.

Saints earn a penalty in the middle of the field and kick to touch close to the try line.

Get over here and they'll secure a bonus point...

The wind is at Northampton's backs in the second half. Alex Mitchell almost finds touch in the Castres 22 with a kick from his own 22, and the return kick by the French side is held up in the gusts before dribbling out of play near halfway.
