Barcelona and Real Madrid are among the sides interested in Bayer Leverkusen's teenager midfielder Kai Havertz, according to Sport Bild.

The German media outlet states the 19-year-old, who is valued at a reported €80m, is on the radar of both clubs along with Bayern Munich, Chelsea and Manchester City.

Now a full Germany international, the rising star has netted 13 goals across all competitions this season with his varying skill set earning him rave reviews within the Bundesliga.

Bayer currently lie in sixth spot in the German top flight and have hit form in recent months following a sluggish start to the campaign.
