It was a busy January transfer window in the Premier League as most of the top teams brought in significant reinforcements for the second half of the season.
There were a handful of high-profile transfers that occurred only after the Premier League season started, such as Alex Oxlade-Chamberlain's move to Liverpool from Arsenal as well as Tottenham's deadline day scoop of Fernando Llorente - as well as Chelsea's last-minute deals for Danny Drinkwater and Davide Zappacosta.
That's because other leagues have different windows and will still be open.
It opened on Monday, May 7 for domestic transfers.
It was over eight months ago that the Premier League voted to make changes to the Summer Transfer Window.
"But before all of that, there is a World Cup to consider, and a lot of clubs and players will want to wait until after Russian Federation because they may get a better offer if the player has a good tournament".
In early September 2017, the headline news was that from now on the window would close before the season kicked off.
That deadline only relates to buying players and the selling or loaning of players will still be able to take place up until August 31 - the deadline for the remainder of Europe. They will still be able to loan players and register players that are free agents up until August 31, 2018.
The thinking being that this would curb the disruption and uncertainty in the past, caused by players being targeted after the games had started and clubs already had their squads finalised, only to then see interest in their key players. With uncertainty as to who is running their teams, what are the chances of those clubs rolling out a smart, strategic transfer strategy later this week, created to avoid a panic-stricken spending spree in the first week of August?
However, rather bizarrely, when the Summer Transfer Window would actually begin, has been shrouded in secrecy, with no official confirmation.
Federation Internationale de Football Association requires each league to have at least one transfer window in a calendar year that lasts for 12 weeks.
Managing the new window will be a challenge, especially as English clubs could find themselves vulnerable to big offers from Spanish or Italian clubs after the Premier League window closes.
But clubs may now be able to snap up their targets before they head off to Russian Federation.
All very unusual as to why the start date has been given such secret treatment.
