The window opens on June 9 for France, July 1 in Italy and Germany, and July 2 in Spain.
Across the world of football, there are plenty of stories that have fans talking.
Here, we look at the latest transfer deals that could happen this summer.
The La Liga champions signed the young Frenchman for £135m just last summer. However, even after returning to fitness, Dembele found first team opportunities hard to come by with former Red Philippe Coutinho being preferred on a regular basis.
Barca are closing in on the signing of Antoine Griezmann and would be open to a loan move for Dembele with a mandatory option to buy.
Despite only joining AC Milan last summer, Leonardo Bonucci is looking for an escape route after the Serie A side failed to qualify for next season’s Champions League.
Due to Financial Fair Play regulations, Milan could be forced to sell.
Sokratis Papastathopoulos is on Arsenal’s radar after deciding against Caglar Soyuncu who was proving to be too expensive, the Daily Mail claims.
The Gunners balked at Freiburg’s demand of £35 million for the Turkey international and have turned to the Borussia Dortmund defender instead.
Although the Greek international is eight years older than Soyuncu, he is valued at around £17.5m.
Domestic dealing can officially begin at one minute past midnight, giving buyers and sellers 12 weeks to do their business, in line with FIFA regulations, before the window closes on the new earlier date of August 9.
However, international transfers cannot be processed until June 8.
A statement on the governing body’s official website, www.premierleague.com, said: “The summer transfer window for Premier League clubs will open at 00:01 on May 17 2018.
“Before then, clubs are able to agree deals for the acquisition of players but, in the case of a domestic transfer, the paperwork cannot be processed until after midnight on May 17, once the window opens.
“The transfer of players from another national association may take place once the FIFA Transfer Matching System (TMS) opens at midnight on June 8 2018.
“This means that any international transfers cannot be processed until the FIFA TMS transfer window opens.
“As agreed by the clubs in September 2017, the summer transfer window will close at 17:00 BST on Thursday, August 9 2018.”
The Premier League has brought forward the deadline in a bid to avoid the kind of disruption which surrounded the likes of Jamie Vardy and Gylfi Sigurdsson last year with the season already under way.
Fourteen of the 20 top-flight clubs at the time voted in favour of the shortened period.
It was a move which was supported by Manchester United boss Jose Mourinho.
He said: “As a football man, as somebody who wants to work with the team, work with players, I would prefer the window to close as soon as possible.”
Newcastle counterpart Rafael Benitez has insisted there will still be more than enough time for clubs to get their business done.
He said: “You had three months to do whatever you wanted to do, now you have two months. You can do whatever you want in two months.”
The Football League, whose window for permanent signings has already reopened, has also confirmed they will comply with the August 9 pre-season deadline.
The summer transfer window is now less than one month away and the rumours of players and coaches potentially being on the move is gathering pace.
Across the world of football, there remains plenty of activity and stories that have football fans talking.
Here, we look at the latest transfer deals that could happen when the market reopens in June.
Manchester City lead the chase to sign the influential West Brom captain. The Daily Mirror reports the Northern Ireland international could leave the club for £3m (Dh 14.8m) following the Baggies’ relegation.
With John Stones slipping down the pecking order and add to that Vincent Kompany’s constant injury problems, Evans’s leadership qualities would make him a fearsome addition at heart of the City defence. A move to the Etihad Stadium would guarantee the potential to win trophies, but it is unlikely he will see first team action on a regular basis if both men are fit.
Chelsea are preparing to launch a bid for Newcastle captain Jamaal Lascelles, reports the Evening Standard. Gary Cahill is 32 and David Luiz is 31, with Chelsea determined to add youth to their squad.
The Blues are keen to bolster their defensive options, and the 24-year-old ticks all the boxes for Antonio Conte’s side. But Rafa Benitez will be desperate to keep hold of Lascelles, who was a close contender to make Gareth Southgate’s World Cup squad.
