Premier League questions: Which Man Utd will turn up, and can Arsenal continue their form?

Ahead of an important round of Premier League fixtures, we take a look at 10 questions that could be answered by the end of the weekend.

With a combined winless run of 13 in the Premier League, who will stop the rot first? (Aston Villa v Swansea, Saturday 3pm)

Villa are without a league win since their opening-day victory at Bournemouth, while Swansea have stuttered since their fine 2-1 win at the end of August against Manchester United.

The pressure on Garry Monk does not compare to that on Tim Sherwood's shoulders, and both clubs would struggle to find a better opponent to get back to winning ways.

Swansea need Bafetimbi Gomis and Andre Ayew firing again after superb early-season form, while the hosts are in danger of sleepwalking to relegation after five straight years of fighting at the bottom of the Premier League.

Swansea won this fixture 1-0 with a late Gomis goal last season, and a repeat would strengthen the buffer between them in mid-table and the struggling pack.

Can Palace bounce back against never-say-die Leicester? (Leicester v Crystal Palace, Saturday 3pm)

Two of this season's surprise packages come head-to-head at the King Power Stadium, with just one point separating them in the top six.

Leicester have already saved seven points from losing positions so far this season, and showed their resilience again last weekend by coming from 2-0 down to grab a draw at Southampton.

Jamie Vardy's form shows no sign of slowing down, and Claudio Ranieri's men face a wounded Palace after their defeat by West Ham with 10 men.

But Leicester should be wary - Palace have bounced back from each defeat this season with a win, and a repeat on Saturday could put them in the top four with 10 games gone.

Can the Baggies drag Norwich down another peg after conceding six at Newcastle? (Norwich v West Brom, Saturday 3pm)

Up to last Sunday, Norwich had been hard to beat, but having had a go at Newcastle at St James' Park, the manner in which they fell will have hurt Alex Neil.

The Canaries have had a poor October, losing at home to Leicester before going down at winless Newcastle, and are currently separated from the bottom three by just three points.

West Brom, meanwhile, grabbed a vital victory over Sunderland last time out, but Tony Pulis will know three points against the struggling Black Cats should not mask some unimpressive performances to date. A dogged yet vital affair awaits.

Can Stoke continue their merry march up the table after a poor start? (Stoke v Watford, Saturday 3pm)

A potential fourth straight win for Mark Hughes' Stoke seemed impossible a month ago after no victory in their opening six games, but the Welshman's side have clicked in the last four weeks.

A thoroughly professional 1-0 win at Swansea on Monday Night Football said much about Stoke's defensive qualities, strangling Monk's typically expressive side after scoring an early penalty.

Bojan Krkic, Marko Arnautovic and Xherdan Shaqiri have been particularly impressive and are giving Stoke a new complexion going forward, while Watford are now three without a win following the 3-0 defeat by Arsenal on Saturday Night Football.

Will Chelsea continue their mini-resurgence against the happy Hammers? (West Ham v Chelsea, Saturday 3pm)

With West Ham unbeaten in six and fourth in the table, is there a less desirable place in the Premier League for Jose Mourinho's Chelsea to visit than Upton Park?

The Hammers' fine 3-1 win at Crystal Palace was their fourth away success of the season, and they now have the chance to prove their home form is up to scratch against a Chelsea side who returned to winning ways against struggling Aston Villa last weekend.

The Blues were not on blistering form at the Bridge on Saturday, and a goalless draw in Kiev in midweek did little to suggest they have fully found their feet again. They will be in for another tough afternoon in east London.

Will Arsenal further prove they are real title contenders after three straight impressive Premier League wins? (Arsenal v Everton, Saturday Night Football, 5.30pm, live on Sky Sports 1)

Having won 5-2 at Leicester, 3-0 at home to Manchester United and 3-0 at Watford, Arsenal are at their blistering best, and find themselves two points off top spot.

Sound familiar? Arsenal have shown flashes of title-winning form plenty of times in the past few years with no title to show for it, and nobody at the Emirates will be more aware than Arsene Wenger that momentum is everything.

Live Ford Saturday Night Football

A 2-0 win over Bayern Munich has brought a buzz to the club, but the Gunners must further shake that peak-and-trough tag with another win on Saturday Night Football.

In Arsenal's favour is the unpredictable nature of the Premier League so far this term, with rivals Manchester City and Manchester United showing sporadic weaknesses, and champions Chelsea's weak defence of the title. 

They face an Everton side on the back of being thoroughly outplayed by United last weekend, but with top four ambitions of their own.

Can Sam Allardyce carry on the bizarre tradition of beating Newcastle with Sunderland in his second game in charge? (Sunderland v Newcastle, Super Sunday, 12pm, live on Sky Sports 1)

History shows that form goes well and truly out the window for this one, and Sam Allardyce will be praying the same is true for Sunday's huge clash at the Stadium of Light.

The timing of Allardyce's appointment is a familiar one; Paolo Di Canio, Gus Poyet and Dick Advocaat all recorded victories over their bitter rivals in their second game in charge, and a repeat will give Sunderland their first win of the season.

Live Ford Super Sunday

The timing of Newcastle's thumping 6-2 win over Norwich could not have been better for Steve McClaren, and he will bring plenty of fans on board if they snatch a win on Teesside on Sunday lunchtime.

But a nervy afternoon is in store for the travelling Toon Army, whose side are without a derby win since way back in August 2011.

Will Spurs return from their trip to Belgium with a victory over struggling Bournemouth? (Bournemouth v Tottenham, Sunday 2.05pm)

Spurs have navigated the Thursday-Sunday conundrum with a win and a draw so far this season, and face an out-of-form Bournemouth on Sunday afternoon after a Europa League tie at Anderlecht.

In fact, Mauricio Pochettino's side are unbeaten in the league since the opening day of the season, but five draws in eight has them sitting just outside the top six with nine games gone.

Bournemouth must prove they can survive in the Premier League without long-term casualties Tyrone Mings, Max Gradel and Callum Wilson, but a defeat could see them in the bottom three by Sunday evening.

Which Man Utd, and which Man City, will turn up for another huge derby? (Man Utd v Man City, Super Sunday, 2.05pm, live on Sky Sports 1)

Sunday's Manchester derby is being billed as the most unpredictable since Sir Alex Ferguson departed Old Trafford.

Both United and City have shown erratic form in their opening nine games, and although the visitors are favourites for the title, United are slight favourites for the clash.

City have won both games since losing David Silva and Sergio Aguero to injury, but the high intensity of the derby may be telling for Aguero's replacement Wilfried Bony, who struggled midweek in the win against Sevilla.

How will Jurgen Klopp's 'pressing game' transfer at Anfield against Southampton? (Liverpool v Southampton, Super Sunday, 4.15pm, live on Sky Sports 1)

From a tactical point of view, Klopp's Liverpool debut in a goalless draw at White Hart Lane brought talk of a high-intensity pressing game, where the Reds became the first team to out-run Spurs this season, and clocked the highest distance and sprints from his adopted side.

But with home games comes an expectation and Klopp's approach when the onus is on Liverpool to attack will be intriguing.

The Saints are unbeaten in three games as they look to continue their resurgence after a slow start, but the 2-2 draw at home to Leicester having been 2-0 up would have hurt confidence.
