The Brazilian youth international spent last season with Dutch side Vitesse, netting 11 times in 29 appearances, having spent a spell with Malaga the year before. He has made just one appearance for the Blues first-team, although he was part of the Under-18 squad that won the FA Youth Cup in 2012 - 24 hours after being named the Blues Young Player of the Year.
He has started both of Frankfurt’s games this season, and speaking to German newspaper Bild, the young Brazilian has revealed that he is enjoying his time enough to consider a permanent move away from West London.
Translated by ESPN, Piazon is quoted as saying: "I think it's normal. Chelsea have so many very good players, and currently it'd be difficult for me to find a place there. Here, I can play here and gather experience.
"I am only 20 now. And like I've said, everything can happen in football. If everything fits, I can certainly imagine staying in Frankfurt. I'll move into my flat next week. And I'll begin language school this week to learn German.”
Whilst expressing a desire to play for Chelsea in the future, the youngster is aware that there are no guarantees - even if he has a good season in the Bundesliga.
"I came to Chelsea directly from Brazil. I know everyone at the club. Of course, I'd wish to play for there again. But football is a bag of tricks, everything can change so fast.
"Malaga was a bit like Brazil. The beach, the sun, easy football. In Netherlands, the language is as complicated as here. But the league was weaker. Everything's more professional in Frankfurt. The Bundesliga is one of the most difficult leagues, and that's why it's fun to play there.”
Piazon is one of 26 players away from Stamford Bridge this season on a temporary deal, and if they can receive a sizeable fee for the transfer of his services, then all parties will likely agree that a move for the youngster is best.
