Mario Gotze's agent Dirk Hebel has confirmed Manchester United and Juventus have both made enquiries over the highly-rated Borussia Dortmund midfielder.
Gotze, 19, has emerged as one of the most sought-after players in European football having impressed for the Bundesliga side since making his first-team debut in 2009.
The German international, who has been linked with a big-money move to Manchester United, scored five goals in 14 appearances before picking up a groin injury that has kept him side-lined since December.
Gotze, capped 12 times by the German national team, is expected to feature prominently in this summer's European Championships in Poland and Ukraine and his agent, Dirk Hebel, has revealed Manchester United and Juventus have both made contact over the midfielder's availability.
"I think in Europe all the top clubs are interested in Mario," Hebel told Calciomercato.com - via Sky Sports.
"I can confirm that I have had contact with Juventus and Manchester United, but not only them.
"I don't know if he'll go away after this season, you should ask Borussia. But I think that they will not let him leave for less than 40million euros. He still is very happy at Dortmund, though now he is injured."
But Manchester United face a battle to sign Gotze in the summer after Dortmund sporting director Michael Zorc insisted the club would strive to retain the midfielder beyond the end of the season.
Speaking to Kicker in January, Zorc said Gotze was unlikely to leave Dortmund before his contract expires in 2014.
"Anyone who plays for a club like Dortmund can only imagine extending their stay there," he said. "But this isn't a current issue. I wouldn't rule it out, but I won't guarantee it."
