So, after a perfect start to the season, what will it take to finally beat Saracens?

We want to hear your thoughts on today's matches.

Get involved using the #bbcrugby on Twitter and we'll post a selection throughout today's live text commentary.

Cheeky bit of brotherly banter from Newcastle back Marcus Watson, who could face sibling Anthony today.

Of course, they're not the only brothers involved - Horacio and Belisario Agulla line up on opposite sides today too.

Bath make three changes with Nick Auterac, Niko Matawalu and Matt Banahan all coming into the starting XV.

Head coach Mike Ford has again opted for Wales playmaker Rhys Priestland alongside Matawalu in the halves ahead of son George - who remains on the bench.

Continuing the family theme, brothers Belisario and Blue, Black and Whites flier Horacio Agulla could come face-to-face on opposite sides, as could fellow widemen Marcus and Anthony Watson.

Replacements: Dunn, Lahiff, Wilson, Day, Louw, Evans, Ford, A.Watson

Argentine playmaker Juan Pablo Socino steps up from the bench to start for Newcastle.

Craig Willis retains his place in the halves, after making his Premiership debut against Leicester on Boxing Day.

Richards has kept faith with the same pack that gave the high-flying Tigers a game at Welford Road.

Replacements: Lawson, Rogers, Ryan, Botha, Clever, Dawson, Catterick, B Agulla.

Last season's beaten Premiership finalists Bath have stuttered this season but will fancy their chances of success at Kingston Park this afternoon - where they have a remarkable record.

However their concerns are nothing compared to opponents Newcastle - who lie bottom of the Premiership and are the only side yet to win in the league this season.

Dean Richards' Falcons put up a big fight at Leicester Tigers on Boxing Day but came away with nothing - made the more significant by London Irish's win against Northampton.

The London Irish team news is nice and simple.

Head coach Tom Coventry has named an unchanged starting XV off the back of their first Premiership victory since April - the 25-23 home win over Northampton on Boxing Day.

Replacements: Ellis, Smallbone, Aulika, Sinclair, Trayfoot, Steele, Geraghty, Ojo.  

Gloucester have made six changes from Sunday's 39-39 draw with Harlequins at Twickenham.

Paul Doran-Jones withdrew earlier in the week, while fellow prop John Afoa, England wing Jonny May and centre Henry Trinder were all injured in the match against Quins.

Scotland captain Greig Laidlaw is rested and replaced by Willi Heinz at scrum-half.

In the pack, Nicky Thomas, who replaced the injured Afoa against Harlequins, continues at tight-head prop, while Nick Wood replaces Dan Murphy and Tom Savage comes in for Mariano Galarza.

Replacements: Lindsay, Murphy, McAllister, Morgan, Rowan, Laidlaw, Burns, Atkinson.  

Gloucester go into today's game at Kingsholm on the back of the news Jonny May will have surgery on a knee injury which could rule him out of the Six Nations.

The Cherry and Whites have had a mixed start to the season with three wins, three losses and that incredible 39-39 draw against Harlequins at Twickenham on Sunday.

London Irish will be full of confidence after picking up their first win of the season against Northampton, but they still sit 11th in the table just two points ahead of bottom side Newcastle.

Leicester's injury-plagued Argentina wing Gonzalo Camacho comes in to make his first start for the club, two and a half years after joining the East Midlands side.

The Tigers have Mathew Tait alongside Seremaia Bai at centre, with Telusa Veainu at full-back.

Owen Williams returns to the squad after recovering from a knee injury suffered in the first leg of the European Champions Cup back-to-back games against Munster.

Replacements: T Youngs, Mulipola, Cole, Fitzgerald, McCaffrey, B Youngs, Williams, Thompstone.  

Saracens make three changes from the side that won at Wasps on Boxing Day.

Centre Marcelo Bosch, fly-half Charlie Hodgson and hooker Schalk Brits return for the home clash against third-placed Leicester Tigers.

Duncan Taylor, Owen Farrell and Jamie George all revert to the bench as coach Mark McCall, who has already used 38 different players this season, continues to rotate his squad.

Replacements: George, Gill, Lamositele, Hamilton, Wray, De Kock, Farrell, Taylor.  

Gloucester, Northampton, Wasps - steamrolled. Sale, London Irish, Worcester, Newcastle - trampled.

Seven games. Seven wins. Saracens finished 2015 top of the table with a 100% record in the Premiership.

But, the New Year brings with it their sternest test to date in the form of third-placed Leicester Tigers - a side that has lost just once this season.

Looking more closely at the form guide between these two sides, Sarries also have the historical edge with Leicester's only victory in their last seven encounters with Saracens in all competitions coming in last season's 31-27 Premiership triumph at Welford Road.

Hopefully we're in for a slightly more exciting afternoon of rugby than we saw yesterday.

Friday's only Premiership game saw Northampton beat Exeter 8-3 in a scrappy encounter at Franklin's Gardens.

Saints hooker Mike Haywood scored a first-half try as Chiefs succumbed to only their second defeat of the season and missed the chance to go above leaders Saracens.

It was a welcome victory for Jim Mallinder's side following their inconsistent start to the season as they closed the gap to fourth-placed Harlequins to two points.

Over the festive period Saracens soared to seventh heaven (see Chris Ashton doing his best impression of a majestic swan), keeping their perfect start to the Premiership season intact to finish 2015 top of the table.

Next up, in a game that has all the hallmarks of being one of the biggest blockbusters of the campaign, is third-placed Leicester Tigers.

The clash of the high-flyers is the main event in today's Premiership offering. Elsewhere Gloucester host a London Irish side that lifted themselves off the bottom of the table with their first win of the season earlier this week, Bath travel to basement side Newcastle and Sale entertain Wasps at AJ Bell Stadium in the day's evening kick-off (17:30 GMT).
