His style of play and Turkish background have seen him dubbed ‘the next Mesut Ozil’ and his star has been shining since the beginning of the current campaign.
Many a club took notice - but Arsenal were linked with a ‘concrete’ interest in the player - something which was later branded completely untrue by the players agent. At the same time Liverpool were also said to be keen on the Turkish international.
He recently announced his commitment to his current club - with a contract extension until 2018.
Here is what he said about the new deal:
"I myself confess this is a difficult situation for HSV and I want to put a sign with the signature. I'm going to put in mind that we get out as quickly as possible down everything. I would like to achieve in the next few years as much as possible with the club."
But he is likely to leave should Hamburg get relegated - a real possibility after seven Bundesliga defeats on the bounce.
HSV gave Borussia Dortmund a good pasting in a shock win at the Imtech Arena - with Calhanoglu adding a late third.
And what a goal it was.
He decided to fire in a free-kick strike from just outside the centre circle - which rocketed into the back of Roman Weidenfeller’s goal.
