Germany youth international Jann-Fiete Arp has said he chose to renew his contract at Hamburg rather than move abroad as it "doesn't make any sense to join Chelsea as a 17-year-old."
After scoring two hat tricks and another goal for Germany in five matches at the recent European Under-21 Championship, Arp reportedly caught the eye of clubs including Chelsea, Borussia Dortmund and Juventus.
In June, however, the 17-year-old committed his future to Hamburg when signing a contract through to 2019.
In an interview with Bild, Arp has explained his decision to stay with the Bundesliga club, where he has scored 28 goals in 25 games for their U17 and U19 teams, and where he has now joined the senior squad as they prepare for the new season.
