There is now less than a month until the new Bundesliga season gets underway, which means clubs up and down the country are busy putting deals in place to strengthen their squads for the new term.

Here, Sports Mole looks at the latest happenings from the German top flight.

Bayer Leverkusen

Christoph Kramer, who was an unlikely starter in the World Cup final in place of Sami Khedira, is definitely not for sale this summer, Bayer have confirmed amid rumoured interest from Napoli.

There has been interest reported in the press from both Bayer and Bayern Munich in Fiorentina attacking full-back Juan Cuadrado.

Bayern Munich

There has been no end to the speculation linking Xherdan Shaqiri with a move away from Bayern, with Liverpool and Juventus strongly linked, but the player himself has finally said that he intends to see out his contract.

Cuadrado has been attracting interest from Bayern, but the Bavarian side are thought to have ended their interest upon finding out that Fiorentina want £30m for the Colombian.

The club have also made enquiries about Borussia Dortmund winger Marco Reus, and although a deal looks unlikely to happen this summer the player is believed to be keen to move next year.

Borussia Dortmund

Although head coach Jurgen Klopp has stoutly denied that centre-back Mats Hummels will join Manchester United this summer, reports have claimed that a fee of £16m has been agreed between the clubs.

With interest too from Bayern in attacking midfielder Reus, the club face a test to keep hold of their best players, although a Reus move to Bayern could happen next summer.

Borussia Monchengladbach

The main talking point from Gladbach this week has been the pursuit of Jordan Ayew from Marseille. An actual transfer looks some way off, but there are reports that the German side will open with a £2.5m bid.

Eintracht Frankfurt

The club's busy summer so far has continued this week as they completed the loan deal of Lucas Piazon from Chelsea for the season. Piazon is their fourth player in so far in the transfer window.

The hunt for another striker continues, however, with Hugo Almeida the latest name linked with a switch back to Germany having previously played for Werder Bremen.

FC Koln

Adil Chihi, recently released by the Bundesliga newcomers, agreed a deal this week to join English Championship side Fulham.

Hannover

Hiroshi Kiyotake left his options open after being relegated with Nuremberg and was the last of their big-name players to leave the club. Kiyotake yesterday agreed a deal to join Hannover despite interest from the likes of Aston Villa.

They also announced another deal in a busy week, with Turkish player Ceyhun Gulselam joining the club from Galatasaray.
