In the January transfer window, Liverpool and Tottenham enjoyed a win in a signing competition with Colombian winger Diaz.
Liverpool brought Louis Diaz to Anfield for an initial price of £37.5 million. The player signed a 5-and-a-half-year contract with Liverpool.
However, as Diaz is a Colombian player, Liverpool will face an overstepping of the quota for players outside England after signing this player.
According to the Rules of the Premier League, a team's 25-man roster requires 8 locally trained players and 17 overseas players.
In this case, Liverpool will cut German goalkeeper Karius to make room for Diaz.
Loris Karius, now 28, is a forgotten german goalkeeper.
In 2018, when Liverpool played against Real Madrid in the Champions League final, the goalkeeper did not perform well. The player has since been loaned to Besiktas and Union Berlin.
Karius's departure will pave the way for Diaz's arrival. The player can help Liverpool to launch a strong challenge to the league title again in the second half.
Liverpool boss Jurgen Klopp is excited about the new players and can't wait to meet them.
Klopp said: I haven't seen him yet! He hadn't been to a training ground yet.
