Known for their frugal spending, Premier League champions Liverpool shockingly parted ways with a record £446.5m in the 2025 summer transfer window.
Arne Slot's Reds have yet to reap the full benefits of the stars they signed, with some taking time to settle, while others have been hampered by injury during their debut campaigns on Merseyside.
However, it is no coincidence that Liverpool ended the calendar year with a strong run of results at the same time that big-money signings Florian Wirtz and Hugo Ekitike hit red-hot form.
The Reds look likely to be active once again in the January transfer window, especially after striker Alexander Isak suffered a major lower-leg injury that required surgery and will see him sidelined for at least a couple of months.
Read on as Sports Mole ranks the top 10 most expensive signings in Liverpool's storied history ahead of any potential business this winter.
