Hamburg chief Frank Arnesen is confident extending the loan of Chelsea defender Jeffrey Bruma.
Bruma has impressed on-loan at Hamburg this season.
Arnesen told Hamburger Morgenpost: "We have had some good conversations with Chelsea, it was mainly about Jeffrey Bruma and his future within the game. They are pleased with his development.
"Chelsea FC is positive about the loan arrangement and its continuation, although they are not 100% certain about this."
