Liverpool goalkeeper Adrian has opened up on what it is like to work under Jurgen Klopp.

Adrian arrived as a free agent at the start of the season and has filled in admirably for Alisson when the Brazilian has been unavailable.

An experienced campaigner at 33, the Spaniard says it is easy working under the enigmatic 50-year-old.

"What Jurgen has achieved here is extraordinary," Adrian told BBC Sport.

"Just look how we are in the league. It is so easy working with him. So easy. He's always smiling, cheerful, optimistic. He's the manager but he behaves like any another member of the team.

"Him being close to us helps us believe in his methods. He's convinced us all of his leadership and abilities by being close to us and proving that whatever is on his mind works in the end.

"Klopp usually tells us that we'll face many problems during the games, so we must be able to fix them. Any team can surprise you with a new system, for example. He's there to guide us. He visualises football very well from the sidelines and transmits this knowledge to the players in a masterful way.

"Training sessions are intense. He does his job passionately and that's exactly how we perform on the pitch. Jurgen is not only a top strategist, but also a great person. The best group management I've seen. Next to the team through thick and thin."
