Bayern Munich's star striker Robert Lewandowski wants to leave the Bundesliga club this summer to seek "a new challenge", his agent told Sport Bild on Wednesday.
"Robert feels that he needs a change and a new challenge in his career," Pini Zahavi told the weekly.
"The managers of Bayern know about it."
Lewandowski, 29, whose Bayern contract runs until 2021, has been linked heavily linked with Real Madrid in the past while Paris Saint-Germain and Premier League giants Chelsea and Manchester United are also understood to be interested.
Madrid, who knocked Bayern out of this season's Uefa Champions League semi-finals on their way to winning a third consecutive European Cup, will monitor developments closely, with star striker Cristiano Ronaldo and Gareth Bale, who scored twice in Saturday's Champions League final win over Liverpool, both saying after the match that they were considering their futures at the Bernabeu.
Lewandowski is one of Europe's most prolific strikers and was the Bundesliga's top scorer in the just-completed season with 29 goals from 30 games. He has scored more than 40 goals in all competitions in each of the past three seasons in Bavaria.
In late February he parted ways with his previous agent of 10 years, Cezary Kucharski, and signed up with Zahavi, one of the most powerful agents in world football.
Zahavi said that "Robert's motivation are not money or a specific club, because almost all top clubs would like to sign up the world's best striker".

He said he hoped Bayern president Uli Hoeness and chief executive Karl-Heinz Rummenigge would understand the player's position.
"Everyone in the Bayern club leadership has their own great career to look back on. They should understand his situation," he told Sport Bild.
Rummenigge told Kicker magazine earlier this month that Bayern fans "do not have to worry about Robert Lewandowski and the relationship with Bayern ... We have a very good one."
Lewandowski joined Bayern from Borussia Dortmund in 2014, and has scored 151 goals in 195 games, topping the Bundesliga scoring charts in two of the past three seasons.
He has tasted league success in every season at Bayern, though he has endured a frustrating run in the Uefa Champions League, exiting at the semi-final stage in three of his four seasons with the club - with a quarter-final defeat coming in 2017.
Lewandowski will lead Poland at the World Cup in Russa next month when they kick off their campaign against Senegal in Moscow. He is his country's all-time leading goalscorer with 52 goals in 93 matches since making his debut in 2008.
