What questions could be answered by the time the final whistles go in the latest round of Premier League matches?
The action starts on Saturday lunchtime as midtable West Ham entertain Champions League-chasing Arsenal at the London Stadium, live on Sky Sports.
Renault Super Sunday sees Everton host Bournemouth, before third-placed Tottenham play Manchester United at the home of football.
Then on Monday night, champions Manchester City face Wolves at the Etihad.
Will Auba stay top of the scoring charts? (West Ham vs Arsenal, live on Sky Sports Premier League from 11:30am on Saturday)
Arsenal striker Pierre-Emerick Aubameyang heads into Saturday lunchtime's clash with West Ham, live on Sky Sports Premier League, as the joint leading scorer in the top flight.
The Gabon international has found the back of the net on 14 occasions so far this season, the same number as Tottenham's Harry Kane.
However, Auba will be confident of adding to his tally at the London Stadium this weekend having scored in each of his last four London league derbies, netting six goals in total, while also providing two assists.
Can Bournemouth tighten up to stop slide? (Everton vs Bournemouth, Sunday, 2.15pm)
Bournemouth only lost two games in the first three months of the season; in the following two-and-a-half months they have lost 10.
Granted there are more fixtures towards the back end of the year, but only Huddersfield have a worse record than Bournemouth over the last six Premier League matches.
The Cherries have looked to the transfer market for a boost with the additions of forward Dominic Solanke and right-back Nathaniel Clyne, with the latter aiming to help a defence that has conceded 15 goals in the last four games.
Eddie Howe admitted after losing to Brighton in the FA Cup that his side have been "easy to score against recently", and that is something they will need to sort if they are to stop sliding further down the table.
Will Solskjaer pass first 'proper test'? (Tottenham vs Manchester United, Sunday, 4.30pm)
If United win at Wembley on Sunday then Ole Gunnar Solskjaer will have made the most successful start of any manager in the club's history, beating Sir Matt Busby's record of winning his first five matches in charge.
But, after securing his latest win against Championship side Reading in the FA Cup, Solskjaer admitted Tottenham will be his first "proper test".
United have so far beaten Cardiff, Huddersfield, Bournemouth and Newcastle in the Premier League under their caretaker manager, and while there is a feel-good factor around the club, this Sunday will show their progress under Solskjaer.
Will the goals continue to flow as they have done so far? Will they keep Harry Kane quiet? And what impact will a trip to Dubai have on the team?
Victory would be a big step forward for United, particularly with no other top-six sides to play in the Premier League until late February.
Will Wolves have another say in the title race? (Manchester City vs Wolves, Monday, 8pm)
Not too many promoted sides impact the Premier League title race as Wolves have already done this season. They drew with Manchester City in August, beat Chelsea in early December and then shocked Tottenham just as they were building momentum heading into the New Year.
From their seven games against the 'big six' this season, Wolves have taken nine points, losing only twice. They also beat Liverpool in the FA Cup on Monday and held City goalless over 120 minutes at the Etihad last season when they met in the Carabao Cup.
Pep Guardiola said City's draw at Molineux earlier this season was a "good point", but with the title race in the balance and City looking to build on their win over Liverpool, only a victory will do this time out for the champions.
Will Liverpool bounce back? (Brighton & Hove Albion vs Liverpool, Saturday 3pm)
Liverpool's 21-match unbeaten run and nine-game winning streak in the Premier League came to an end at Manchester City last time out.
With Jurgen Klopp's side playing before the champions, though, this will be a great opportunity to stretch their lead at the top of the table back to seven points again, at least until second-placed City are in action at home to Wolves on Monday Night Football.
Will Burnley's momentum continue against travel-sick Fulham? (Burnley vs Fulham, Saturday 3pm)
Burnley host fellow strugglers Fulham on Saturday afternoon hoping to build on some recent good form in the Premier League.
The Clarets had been languishing in the relegation zone prior to them winning their last two league games, picking up more points than they had in their previous 12 matches (five).
But those victories have seen Sean Dyche's side move up to 16th in the table and they will expect to make it three straight wins against the only top-flight team yet to win away this season.
Will Huddersfield end their long losing run? (Cardiff City vs Huddersfield Town, Saturday 3pm)
Things are getting really serious for bottom-of-the-table Huddersfield, who are in danger of getting cut adrift at the foot of the Premier League are a dreadful losing run over Christmas.
The Terriers have lost their last eight league games, their worst run in league football, and a ninth straight defeat at 17th-placed Cardiff would leave them 11 points behind their opponents this Saturday.
Can defensively-sound Eagles start scoring at home? (Crystal Palace vs Watford, Saturday 3pm)
Things are looking up for Crystal Palace, who are sitting more comfortably in 14th place ahead of Saturday afternoon's visit of eighth-placed Watford to Selhurst Park.
Roy Hodgson's side have been a bit of an anomaly at home this season, though, struggling to score, yet being hard to breach as well.
In fact, the Eagles have failed to net in more games at Selhurst Park than any other Premier League side this season, while only Liverpool (7) and Chelsea (5) have kept more home shutouts this campaign than Palace (4).
Will Saints start to climb the table? (Leicester City vs Southampton, Saturday 3pm)
Ralph Hasenhuttl might not have been able to lift Southampton out of the relegation zone yet, but club legend Matt Le Tissier thinks he has made a positive impact.
"I've been very impressed with the training I've watched and the difference in the performance of the team since Ralph has come in and am confident for the rest of the season," Le Tissier said this week.
Ahead of a reunion with former manager Claude Puel, Saints are third from bottom in the Premier League, two points from safety, and without a win in their last four matches.
While performances seem to have improved, they need results to follow soon, particularly with games against Cardiff, Burnley and Fulham coming up in the next two months.
What's Maurizio Sarri's solution? (Chelsea vs Newcastle United, Saturday 5.30pm)
Having lost 1-0 at home to Leicester before Christmas, Chelsea started the New Year with a goalless draw against Southampton that saw some of their fans boo at the full-time whistle.
Chelsea have not gone three games without a goal in the top flight since 1993, but how can Maurizio Sarri fix the goal-scoring issue?
He has tried playing Eden Hazard as a false nine without great success while Alvaro Morata looks short of confidence and Olivier Giroud is just returning from injury. Sarri hinted at a need for an attacking signing after the draw with Southampton, but Chelsea surely need to find a more immediate solution if they are to hold off Arsenal and Manchester United in the battle for fourth.
