The Liverpool board brought in only three players during the summer, with Sepp van den Berg, Harvey Elliott and Adrian joining the squad.
With various players exiting the club, including first-team players like Alberto Moreno and Daniel Sturridge, many questioned as to why there were not more acquisitions.
Liverpool are now only a few injuries away from looking short across the pitch.
Express Sport takes a look at some possible players that Liverpool should be looking at closely during the international break with regards to the upcoming January transfer window.
Kai Havertz, midfielder, Bayer Leverkusen
The 20 year-old Leverkusen star is one of the hottest prospects in Europe and talkSPORT reported Liverpool’s interest in the summer.
Since losing Philippe Coutinho to Barcelona in January 2018, Liverpool have still not found a truly creative force from the midfield that can replace what Coutinho’s departure lost.
Havertz was a force last season, scoring 20 goals and providing seven assists for the German team.
The youngster’s contract expires in 2022 so he is likely to be an expensive purchase if Liverpool do pursue the player in the near future.
However, he may be well worth the expense with Havertz’s sky-high potential in full view of everyone.

Sergi Roberto, defender, Barcelona
With Trent Alexander-Arnold and Joe Gomez the two right-back options, and Andrew Robertson the only true left-back option, Klopp is only a couple of injuries away from a crisis at full-back.
An extremely versatile player who is capable of playing in both full-back positions, Roberto would be an excellent addition to the squad, as he would provide cover for both full-back positions, whilst his ability to play in midfield would also provide further options for Klopp.
The defender’s contract expires in 2022, meaning he would not be available at a cut price deal yet.
However, his versatility and experience he could provide for the squad would be invaluable regardless.

Dusan Tadic, forward, Ajax
A crucial part of Ajax’s run to the semi-finals of the Champions League last year, former (doesn’t need ‘the’) Southampton player Tadic would be an ideal fit at Liverpool.
Liverpool are somewhat short in the left wing position, with only Divock Origi a viable replacement for superstar Sadio Mane.
Tadic plays primarily on the left-side or through the middle of the attack, making him an ideal rotation option for the front three.
Although Tadic extended his contract with the Dutch club until 2023 during the summer, if Liverpool do come calling, the opportunity to join the current European champions may be too good to pass up.
