Starting with the English transfer market, the time and date of the summer deadline in England have traditionally stayed the same, August 31st at 23:59. Although, on occasion the deadline has been changed if the last day happens to fall on a weekend, for example, then the deadline would normally be changed to the following Monday. This year, however, the time and date remain the same.
The date chosen in Spain for the transfer deadline this year is slightly unusual. Spanish teams will have at least 24 hours more than teams from the top European leagues to complete their transfer business, with the window closing on September 1st at 23:59.
In terms of the rest of Europe, the other major leagues all have the same transfer deadline day as England, although the exact hours differ slightly.
Germany will be the first country to close its market, with Bundesliga clubs having to conclude any incoming deals by 18:00. Five hours later at 23:00, the same will be the case for any Italian Serie A clubs. Ligue 1 teams, on the other hand, will have the extra hour to rush through any deals as they have the same deadline as England, 23:59.
Given that the Spanish market is open for at least 24 hours longer than any of the other major European leagues, that could prove very significant for various important deals involving Premier League clubs, such as Diego Costa to Atletico Madrid and Philippe Coutinho to Barcelona. Chelsea and Liverpool will have to wait an extra day to be certain about their respective players' immediate future.
It isn't just Spain whose transfer deadline differs slightly, there are a number of countries whose deadlines differ by a few days, or even weeks.
For example, Portuguese teams will have up until September 22nd to conclude any transfer dealings, and teams in Turkey will have up until September 8th.
The fact that teams from other countries can still come in for players at clubs whose deadlines have already closed is a worry for many managers and owners, but it also gives an opportunity to any clubs looking to offload players after their own domestic deadline.
It is definitely something which needs to be considered, as Premier League sides are set to discuss bringing forward the transfer deadline in England to before the start of the season.
With just one day to go until the deadline for the major European leagues, England is the clear leader in terms of spending over the summer. English teams have spent around a whopping €1.62 billion in total this summer. Italy is in second place with €1.17bn. Spain takes third place with €1.14bn. Germany, with €861m is in fourth and France, with €813m is in fifth, although that could be set to change with the pending confirmation of Mbappe's move to Paris Saint-Germain.
