Bayern München midfielder Douglas Costa is of the opinion that Pep Guardiola is football-mad and can't get enough of the game.
Douglas took time out to praise outgoing Bayern head coach Guardiola and believes the Spaniard's success is based around his addiction to the game.
"When I arrived at Bayern he asked me: 'How are you? Are you ready to learn how to play football?" the Brazil international told Globo Esporte.
"Before, I thought the coach's job was just to set up the team. However, with Guardiola, it's something different. He is addicted to football and because of that he is a phenomenon."
Douglas' football has come alive under Guardiola and the 25-year-old has contributed seven assists for the Bavarian giants.
"At Shakhtar, I got back to defend more. Now I help Bayern score a lot, but I attack more," he said. "Guardiola can get the best out of everyone and that's why he is what he is."
