Adrian has opened up on what life is like working under Jurgen Klopp at Liverpool.
The German has transformed the fortunes of the Anfield club since taking charge in the autumn of 2015, leading them to European and World glory last year.
While Klopp is also on course to end Liverpool’s 30-year wait for a league title, with his side now just six wins away from being crowned Premier League champions.
And Adrian, who joined Liverpool from West Ham on a free transfer last summer, has revealed the type of mentality the German has installed in his Reds stars and why he is best in world football for him.
"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."
