German international Christoph Kramer has left Bayer Leverkusen to rejoin Borussia Moenchengladbach, the buying club said in a statement released on Wednesday.

The 25-year-old midfielder has signed a five-year contract tying him to Gladbach until June 2021.

He previously spent two years at Gladbach from 2013 to 2015, on loan from Leverkusen.

"A year ago we regretfully let Christoph return to Leverkusen and we are even more delighted now that he can come back to Moenchengladbach," said sports director Max Eberl.

Kramer was part of the Germany squad that won the World Cup in Brazil in 2014 during his previous spell at Moenchengladbach but wasn't picked for Euro 2016.

He played 73 times for Borussia during his previously spell while he also went on loan to Bochum in the German second division after originally breaking into the Leverkusen reserve side in 2010.

He played 28 times in the league for Leverkusen last season but his position in the side was set to come under threat from Charles Aranguiz and new-signing Julian Baumgartlinger.

Leverkusen finished third in the Bundesliga, one place above Gladbach.

Kramer will fill the void created at Gladbach by Switzerland international Granit Xhaka's move to Arsenal.
