FC Cologne goalkeeper Timo Horn is on the radar of Liverpool boss Jurgen Klopp.
Simon Mignolet was outstanding for Liverpool in Saturday's 0-0 draw at Tottenham on Saturday.
However, the Cologne Express says Horn is high on the shopping list of Klopp ahead of the January market.
Aware of the rumours, Cologne sports chief Jörg Schmadtke said: "Jurgen hasn't yet called us."
Horn is tied to Cologne until 2019, but this deal includes the affordable buyout clause of €9 million.
