The Serbia international wants a move back to Paris Saint Germain but he also claims he is being tracked by Atletico Madrid.
Ljuboja said: “I cannot imagine another option than leaving. I am under contract for two years but I don’t think that Hamburg will prevent me from moving.
“The German press say I can leave for €5 million, but I think I can go for just a million.
“I have contacts in Spain, and Atletico are still tracking me. I know the French league very well, and that is where I had so much fun.
“I am aware of the rumours than bring me to St Etienne and Lens. These are interesting options. I know very well both coaches. But if one day I have the opportunity to come back to PSG, I will go running!”
