Sebastian Rode signs for Borussia Dortmund from Bayern Munich

Borussia Dortmund have announced the signing of Bayern Munich midfielder Sebastian Rode.

Rode, 25, has signed a four-year deal at the Westfalenstadion.

Two years after joining Bayern on a free transfer from Eintracht Frankfurt, Rode has decided to seek a new challenge after playing just over 500 minutes of football in all competitions last term.

The midfielder arrived at Dortmund on Monday morning, and after passing a medical put pen to paper on the four-year deal at the Westfalenstadion. BVB reportedly agreed a transfer fee between €12-15 million for the former Germany under-21 international.

In recent weeks, he had been linked with several Bundesliga clubs including Wolfsburg, Borussia Monchengladbach, Bayer Leverkusen and Schalke as well as one Premier League side, believed to be Tottenham Hotspur.

Rode is Borussia Dortmund's fourth signing of the summer after already completing the transfers of Osasuna's Mikel Merino and Rennes youngster Ousmane Dembele, and activating Marc Bartra's €8m release clause at Barcelona.

Some media reports had suggested that Barcelona wanted to include a buy-back option, but BVB CEO Hans-Joachim Watzke dismissed that in kicker, saying: "There is no buy-back option."

Dortmund, however, have stopped negotiations with Bayer Leverkusen over the transfer of centre-back Omer Toprak, 26, who is under contract at the Bay-Arena until 2018, but can trigger a €12m release-clause next summer.

"Omer Toprak will not join us this year," Watzke said. "We'd like to think that we are well stocked in central defence."

Kicker, however, added that Bayer Leverkusen believe Toprak and Dortmund have already agreed on a transfer in 2017, when the defenders release-clause kicks in.

Meanwhile, Dortmund have already sold two key players this summer in Mats Hummels, who will join Bayern Munich, and Manchester City-bound Ilkay Gundogan but could yet lose a third.

They have yet to tie Henrikh Mkhitaryan to a new deal, and kicker report that Dortmund could cash in on the midfielder.

The Armenia international is under contract at Dortmund until 2017, and kicker said that an offer in the region of €35m could make BVB reconsider their stance of not wanting to lose Hummels, Gundogan and Mkhitaryan.

Sources close to Arsenal have told ESPN FC the Gunners are priortising a move for the Dortmund man over other targets.
