Per the source, Atleti are keen on the Turkish international attacking midfielder and are prepared to offer €20 million for his services.
In a recent interview with the BILD, Calhanoglu could not rule out leaving Bayer but also said that should he stay he is fully committed to the team.
When asked if he will stay at Bayer Leverkusen, Calhanoglu responded by saying: “You never know in football what will happen.”
Calhanoglu does however, believe he will stay at the club over the summer and that the current crop of players have a lot of potential.
“But this season I will stay. I will now aim to take the next step forward and be successful at this youthful team that has a lot of potential.”
The 22-year-old has revealed in the past that he wants to play in England or Spain in the future and Atleti would be able to offer him Champions League football as well as a title fight.
Bayer reportedly want to cash in on Calhanoglu after three-successful seasons in the Bundesliga but considering he has another three-seasons left on his contract the German giants will only accept a bid that matches their valuation.
