Who is looking to strengthen in the January transfer window?
When the new year arrives at the weekend, Premier League clubs will be able to splash the cash again in a one-month transfer window which could define how things pan out come May.
In seasons gone by, Luis Suarez, Nemanja Vidic and Philippe Coutinho were among those who arrived at English clubs during the winter window, while Juan Mata, Fernando Torres and Andy Carroll all made big-money switches across the country.
Here, Press Association Sport looks at what the 20 top-flight clubs may do once business opens again on January 1.
While new arrivals could sustain a title charge, sorting the futures of Alexis Sanchez, Mesut Ozil and even Arsene Wenger are higher on the list of priorities. Wenger could consider full-back cover for Hector Bellerin and a swoop for a proven Premier League goalscorer, while a long-lasting link with Borussia Dortmund's Marco Reus has once more surfaced.
Eddie Howe declared himself "very happy" with his squad, which suggests the Cherries will let the window open and close without doing much business in-between. However, with that in mind, signing current loanee Nathan Ake on a permanent arrangement from Chelsea is something Howe could explore should it be a possibility.
Sean Dyche will be monitoring Joey Barton's situation with the Football Association with interest as a potential ban for misconduct in relation to alleged betting could scupper the Turf Moor return he agreed prior to Christmas. Elsewhere, a collapsed summer deadline-day move for Poland winger Kamil Grosicki was evidence that the Clarets know they need more pace and guile going forward.
Expect Chelsea, rejuvenated under Antonio Conte, to move only if some of the biggest names become available in the winter window. Conte will have money in his pocket thanks to Oscar's shock transfer to China, though he may promote from within, and Kurt Zouma's return from injury provides defensive reinforcements.
New boss Sam Allardyce will get an early chance to make his mark on the Palace squad having replaced Alan Pardew just before Christmas. Long-term injuries to Connor Wickham and Pape Souare mean forward and left-back are areas of need, and Allardyce will be backed to find replacements, as he was this time last year with Sunderland.
The Toffees could be one of the busier teams in this window given Ronald Koeman's overhaul at Everton is only just beginning and he needs to add goals and creativity as soon as possible. Koeman has already expressed his admiration for Manchester United's Memphis Depay and the Dutchman's out-of-favour colleague Morgan Schneiderlin could be reunited with his ex-Southampton boss on Merseyside too.
Mike Phelan's January activity could determine whether the Tigers are heading straight back to the second tier, and landing a striker after Will Keane's knee injury is paramount. St Etienne winger Oussama Tannane and Lazio's Ravel Morrison have been linked too but the ownership issue is likely to muddy the waters again.
Genk midfielder Wilfred Ndidi could be the first face Claudio Ranieri adds to his Foxes ranks and the Italian will hope he can serve as a replacement for N'Golo Kante. Sporting Lisbon's Adrien Silva said in the summer he wanted to join the champions so they may return with another offer in January.
Question marks persist about Liverpool's defence, hence the Virgil van Dijk rumours, but any January splurges could be made with more of an eye towards next season. Danny Ings' injury and Daniel Sturridge's fitness issues may tempt Jurgen Klopp to try and reinforce his attacking options with American Christian Pulisic from former club Borussia Dortmund, who seem unwilling to sell at this stage.
Anyone who has seen a Manchester City game this season will know new defenders are needed if Pep Guardiola is to achieve success, though the manager has warned there will not be a raft of mid-season signings. Gabriel Jesus, already capped by Brazil despite being just 19, will officially link up with City in January too.
Jose Mourinho still needs to improve United's defence and could move for long-time target Victor Lindelof, the Benfica defender and Sweden international. Otherwise it will be a case of who is departing Old Trafford, with Schneiderlin having already told Mourinho he wants out and Depay set to be among those following him.
There may be more leaving the Riverside than arriving in January, with Jordan Rhodes and David Nugent just two of the players struggling to break into Aitor Karanka's team. Sales may help fund an acquisition or two and there is thought to be interest in Swansea's Gylfi Sigurdsson should the South Wales club decide to cash in.
An over-reliance on Charlie Austin meant Southampton needed a new striker even before the ex-QPR forward got injured and FC Utrecht's Sebastien Haller could fulfil that criteria. Saints would like to keep hold of their central-defensive duo Jose Fonte and Van Dijk with the division's bigger clubs once again focusing their gaze on Saints' ranks.
Expect Mark Hughes to be at the front of the queue in the pursuit of West Brom's Saido Berahino having failed to lure him away from the Hawthorns in the summer. Goalkeeper Lee Grant's loan from Derby is due to expire as well and with Jack Butland suffering another injury setback, the Potters have to keep their current number one in Staffordshire.
The message emanating from the Stadium of Light is that David Moyes will have "very limited" funds as he tries to steer the Black Cats to safety. That makes free-agent acquisitions, such as Joleon Lescott and Leon Osman - both of whom worked under Moyes at Everton - more realistic possibilities unless funds can be generated by selling the likes of Wahbi Khazri.
The beleaguered Swans need to decide who they are going to appoint as Bob Bradley's successor before determining who to add to the playing staff. A centre-back, midfielder and forward are all areas of need and Barcelona's Aleix Vidal, Tottenham's Tom Carroll and Newcastle's Aleksandar Mitrovic have all been on the wish-list.
Moussa Sissoko has not proved to be the answer in an attacking-midfield sense which means Spurs could consider moving for the likes of Ross Barkley, Wilfried Zaha and Isco. Yet it is more likely they snap up a youngster from lower down the Football League pyramid such as Fulham's Ryan Sessegnon.
Amid concerns that Roberto Pereyra's knee injury has ended his season, the Hornets have targeted midfield as the department which requires strengthening. Ex-Watford midfielder Ashley Young, now with Manchester United, would make sense as a loan and Porto's Yacine Brahimi is another name doing the rounds.
Tony Pulis has confirmed a bid has been lodged for Schneiderlin, who is one of a quintet the Baggies are already making moves to acquire. Leicester's Jeff Schlupp is another Pulis would like to bring in but Jay Rodriguez's return to the Southampton team means he is unlikely to be among those heading for the Hawthorns next month.
A right-back and a striker are top of Slaven Bilic's wish list, as they were in the summer, while keeping Dimitri Payet is imperative. Matteo Darmian may be the ideal fit as a defender and long-time target Carlos Bacca would appear to be more attainable than Liverpool's Sturridge.
