Chelsea are pursuing Bayer Leverkusen midfielder Hakan Calhanoglu.

Ajansspor says Stamford Bridge chiefs will trigger Calhanoglu's £33.2m (€38m) release clause.

And it's claimed they plan to hand Calhanoglu a three-year deal.

The Turkey international's agent Bektas Demirtas has already reportedly conducted a preliminary meeting with Chelsea.

Demirtas last week opened the door to a move away from Leverkusen for Calhanoglu.

He said: "Hakan will be [under contract] at Leverkusen for three years.

"If an offer comes along that is fine for Bayer and which also fits with Hakan, we will do a transfer. But the final decision lies with the club."
