All the latest summer transfer news from the Bundesliga...
Bayern Munich are fairly well stocked in the centre of midfield, but with rumours of interest in Juventus' Arturo Vidal, it seems Pep Guardiola is still looking for more. Assistant coach Hermann Gerland has risked angering Bundesliga rivals Schalke by suggesting that their midfield star Leon Goretzka, 19, must play for Bayern at some point in his career having earned a call-up to Joachim Loew's preliminary Germany squad for the World Cup.
"Goretzka is of the level to play at Bayern Munich," said Gerland. "Now he has signed a long-term contract at Schalke, but if you’re as good as he is, he must also play for Bayern during his career."
If Goretzka does move to Bayern sooner rather than later, then Schalke could already have a potential replacement lined up. Dinamo Zagreb midfielder Marcelo Brozovic, 21, was selected in Niko Kovac's World Cup squad and came off the bench in the opening game against Brazil. With hopes that he could emulate the success of compatriots Luka Modric, Ivan Rakitic and Mateo Kovacic, there is plenty of interest in Brozovic - but Dinamo insist that he isn't for sale despite Schalke's wishes.
"Currently there are no offers for him. A long time ago [Inter] offered 4million euros (£3.2m), but we said no. We do not intend to sell him because he is in our plans to create a Dinamo side that can do well in Europe," said vice-president Zdravko Mamic.
Meanwhile, Bayer Leverkusen continue to add to their squad with the capture of Shakhtar Donetsk youngster Vladlen Yurchenko. The 20-year-old midfielder has signed a two-year deal at the BayArena, and sporting director Rudi Voller told of his delight at the signing.
"In Vladlen Yurchenko we have signed another talented player ready to take the next big step in his career," Voller told Leverkusen's official website. "This transfer fits in perfectly with our philosophy of giving promising young players the chance to show what they can do at the top of the game perhaps earlier than other clubs."
