Hakan Calhanoglu was one of Hamburg's stand-out players in 2013/14.

Bayer Leverkusen chief executive Michael Schade has announced that Hakan Calhanoglu has verbally accepted a deal to join the club.

The 20-year-old attacking midfielder is highly-rated following an impressive first season in the Bundesliga - scoring 11 goals in 32 appearances.

German national newspaper Bild have reported that Leverkusen have made an offer worth around €12.5million and that they plan to offer somewhere around €3million-per-year to Calhanoglu.

We have an understanding with the player. He has verbally accepted our offer and only wants to join us, he has informed Hamburg of this Michael Schade

Schade seems confident that the Turkish international will join the club this summer.

“Calhanoglu should become our marquee signing. We have presented an offer in writing to HSV," Schade told Bild.

“We have an understanding with the player. He has verbally accepted our offer and only wants to join us, he has informed Hamburg of this.”

Despite Schade's comments Hamburg are believed to be keen to retain Calhanoglu's services ahead of the new season.
