Leandro Cabrera (Espanyol)
Arrived from Getafe, the Uruguayan player reportedly has a buyout clause of 15 million euros. At the age of 28, he would accept the role of a substitute without problems.
Dan-Axel Zagadou (Borussia Dortmund)
Having arrived in Germany from PSG, he is a promising U-21 international, but Favre has barely given him any time recently. Zagadou can play at full-back, which would be interesting, but would cost around 30 million euros.
Tanguy Kouassi (PSG)
One of the great promises of PSG and already in the first team despite being only 17 years old. Several teams are following him and it won't be easy to get him out of the Parisian club. Moreover, he lacks the experience necessary to perform from day one in Liverpool.
Zou Feddal (Betis)
An affordable, veteran option with immediate return. Morocco's Zou Feddal would cost Liverpool a mere five million euros, although he would be the oldest and least productive player in the club's network in the long run.
