Time is ticking.
The early finish to this year's transfer window - at 17:00 BST on Thursday - may see clubs scrambling around for some late deals.
Will Tottenham finally sign a player? Will Anthony Martial remain at Manchester United?
BBC Sport takes a look at nine players that may be packing their bags before the deadline.
Toby Alderweireld (Tottenham)
Belgium defender Alderweireld struggled to regain his place in the Tottenham side after an injury lay-off last season, having previously been a regular starter for Mauricio Pochettino's side.
Alderweireld's contract expires at the end of the season and while Manchester United are interested, the reported £75m asking fee could be a stumbling block.
Jack Grealish (Aston Villa)
England Under-21 international Grealish performed superbly in Villa's run to the Championship play-off final, where they were beaten to top-flight promotion by Fulham.
The Midlands side have financial problems and Grealish has caught the eye of Tottenham, who want to sign him for £20m, but manager Steve Bruce wants double that amount.
Danny Ings (Liverpool)
Once capped England striker Ings has endured a frustrating three seasons at Anfield and found the net just once in the Premier League last term.
That has not deterred the Reds from placing a price tag of at least £20m on the player, with reports suggesting Crystal Palace could seal a deal.
Harry Maguire (Leicester)
Solid centre-back Maguire has turned into a dependable starter for both club and country and his stock grew after his performances for England at the World Cup.
Jose Mourinho is eyeing the Yorkshireman up in a £65m deal for Manchester United, although Leicester are reportedly keen for a fee closer to £80m, which would be a world record for a defender.
Anthony Martial (Manchester United)
Martial has struggled for first-team opportunities at Manchester United since the arrival of Alexis Sanchez and he missed out on a place in the France squad for their triumphant World Cup campaign.
Mourinho was reportedly unhappy that Martial left the club's pre-season tour in the US to fly to France for the birth of his second child and is willing to cash in for £80m.
Simon Mignolet (Liverpool)
Belgium goalkeeper Mignolet was number two to Karius for much of last season and he has dropped further back after the big money arrival of Brazil number one Alisson from Roma.
Surprisingly, La Liga champions Barcelona are interested in making Mignolet back-up to number one Marc-Andre Ter Stegen, while Turkish side Besiktas could be keen as they are looking for a new keeper after selling Fabri to Fulham.
Aaron Ramsey (Arsenal)
Wales international midfielder Ramsey has completed 10 seasons at Arsenal, playing over 300 games, but may fancy a new challenge as he enters the final year of his contract.
New boss Unai Emery has called Ramsey an "important player", but rivals Chelsea are reported to be lining up a £35m move and Liverpool hold an interest too. Will Arsenal cash in?
Willian (Chelsea)
Hardworking winger Willian started all five of Brazil's games in their run to the quarter-finals of the World Cup, but his relationship with Chelsea has been uneasy after being left out of the FA Cup final win over Manchester United by former boss Antonio Conte at the end of last season.
Willian missed the first scheduled day of training for the new season because of a passport issue, and £65m may be enough for his signature with Real Madrid strongly linked.
Wilfried Zaha (Crystal Palace)
Despite missing the first five weeks of last season, pacy winger Zaha notched nine goals and three assists for a Palace side who struggled all campaign at the wrong end of the table.
Manager Roy Hodgson has said he wants the Ivory Coast international to stay at Selhurst Park, but a big money offer may tempt them to sell.
