Liverpool may be blazing a trail this season when it comes to scoring goals and creating chances, but boss Jurgen Klopp isn't naive enough to think it can last forever.
As the previous campaign highlighted, goals can dry up even across the most prolific of forward lines. And now, with the likes of Mohamed Salah and Sadio Mane needed by their countries for the upcoming African Cup of Nations, the Reds know it is time to bring in the reinforcements.
Given the rigid transfer policy at Anfield, it remains unlikely that Klopp will be allowed to splurge on a striker in January, meaning a big summer move could - and should - be in the offing.
