Jurgen Klopp's first summer at the club looks likely to be a busy one.
This is of little surprise of course. Liverpool appointed Jurgen Klopp as their manager in October and practically no business was done to address the squad at his disposal in the short term - only Steven Caulker on an emergency loan deal was added to the squad from January. He has given this side a fair crack of the whip, and changes are on the way.
He has, of course, already made steps in that direction - by securing the signing of teenage midfielder Marko Grujic from Red Star Belgrade for £5.1 million, who will link up with the Reds in the summer, and signing central defender Joel Matip from Schalke on a pre-contract agreement.
That seems to be only the start of what is going to be the third incredibly busy summer transfer window in as many years as the Reds seek to restore themselves towards the top of English and European football once again.
The truth is Liverpool can't keep going on with extensive overhauls at the club. This really has to be the big one under Jurgen Klopp. That, of course, doesn't mean there can't be windows where alterations are made to the side, but there has to be a time when the scale of business done by Liverpool is a little smaller than it has been in recent years.
Klopp does have a track record of bringing in several new faces before the start of a season during his time at Borussia Dortmund, where his success along with his other qualities is what got people on the red half of Merseyside so excited about his appointment in the first place.
While the previous two summer windows have been under Brendan Rodgers, there are going to be some looking in at Anfield wondering whether it is the right club for them if they keep on turning over players at the rate of the last two summers.
Of course, Klopp needs to get his players in in order for the Reds to kick on next season. He needs players that fit his blueprint, he practically needs to address all areas of the team - some are more urgent need than most.
He needs to find a way to get Liverpool firing regularly at one end of the field and tight at the other - players that won't contribute silly errors that seem so needless, yet prove so costly.
More steel, more solidity and more firepower - the bulk of which has to be done in this window, and early. Only then can we really see what Jurgen Klopp's Liverpool is supposed to look like.
