There wasn't much in the way of fanfare, and there certainly wasn't the same hullabaloo as when, as we are required by law to state, it slams shut in August.
But the transfer window officially opened on Thursday, at least for moves between English clubs.
Any international deals will have to wait until June 11 to be ratified.
Regardless, in reality clubs never stop pursuing transfers. The window is merely a time period in which agreements can be made official and moves actually completed.
Three alternative signings to Philippe Coutinho that Liverpool could target this summer
Behind the scenes, for months scouts will have been traversing the globe, targets will have been identified, funds will have been discussed, tentative enquiries made.
Liverpool are no different. And Jurgen Klopp has, for some time now, been consistent over what business he expects to be done during the summer.
It isn't much. Having splashed out more than £170million last year to bring in Alisson Becker, Naby Keita, Fabinho and Xherdan Shaqiri, there won't be the same amount of expenditure this time around.
Not least because Klopp believes that, with the return to fitness of Alex Oxlade-Chamberlain and Joe Gomez, along with high hopes of a first-team breakthrough for Rhian Brewster, Liverpool's squad will be stronger next term regardless of any incomings.
That's not to say there won't be any new faces.
Natural wastage from the squad - Daniel Sturridge and Alberto Moreno will leave, the likes of Simon Mignolet and Nathaniel Clyne will surely consider a departure - means certain players will have to be replaced, ensuring a continued depth of options.
But when it comes to players that will step straight into the first team, Klopp has played down such talk.
And there's a very good reason for that.
With a club-record 97 points accrued in the Premier League and a Champions League final on the horizon, there is precious little scope for improvement.
Of course, it's always easier to attract reinforcements from a position of strength. And rarely if ever during the past 30 years have Liverpool seemed such an attractive proposition to interested players.
However, the pool of talent that can improve the Reds is shrinking with almost every campaign.
Even then, the clubs where these players reside are likely to be direct rivals to Liverpool who, given the huge financial rewards for leading teams in the modern era, are less inclined to be under pressure to sell for anything but a ridiculous fee.
How Man City will shape Liverpool's pre-season plans under Jurgen Klopp
Witness Liverpool's sale of Philippe Coutinho to Barcelona for £142million, for example.
The Reds have been creative in recent years by snaffling the best from relegated clubs - an avenue down which they may well travel again this summer - and they've also asserted a certain shift in power by taking Alex Oxlade-Chamberlain from Arsenal.
Now, though, is when things become a little trickier.
Manchester City found themselves in a similar position this time last year.
Having strolled to the Premier League title, won the League Cup and gone deep into the Champions League - you might remember who eliminated them at the quarter-final stage - and with a squad still possessing sufficient youth, Pep Guardiola knew he didn't need a major overhaul.
Their one big purchase was Riyad Mahrez for £60million from Leicester City, and even then they'd initially wanted the player in the January.
City will look to spend again in the coming months but, as with Liverpool, they'll have the same issue. More players than ever will want to join - few will be good enough or available enough to do so.
The Reds will make new signings. They may, if the opportunity arises, make a big-name, big-money purchase if the right player becomes available at a price impossible to resist. That's the way of any ambitious club.
But if it's a relatively quiet few months, it'll be easy to understand why. The market has got a whole lot smaller thanks to the huge strides made under Klopp during the past 18 months.
