Valero, who has returned to Liverpool from West Ham, believes that Alisson is the best goalkeeper in the world. He mentions that it's his responsibility to keep the standards high in the goalkeeping position.

The team is lucky to have both Alisson and Mamardashvili, according to Valero. Alisson has been a top goalkeeper for many years, and Mamardashvili has huge potential to become a top goalkeeper in the future.

Mamardashvili has shown his skills in La Liga with Valencia, and Valero believes that he is the best young goalkeeper in Europe. Valero is confident that Mamardashvili will continue to grow and improve as a goalkeeper.

The team has a strong set-up with both Alisson and Mamardashvili, and Valero is excited to work with them.
