Chelsea brought the Brazillian from Sao Paulo in 2011, and have loaned him out to Malaga last season and Dutch side Vitesse this season.
Piazon told Brazillian sports website Lancenet: "I'm only 19 and have already played in three leagues, and that was good to me.
"The experience at Malaga and this one are important to make me mature, I don't regret anything."
Chelsea keep tabs on their loaned players, and Piazon added: "Chelsea have staff just to follow the loaned players, they always send emails telling me what I am doing right, wrong, what I have to improve.
"They send a summary about that, with my strengths and weaknesses, they are always following my progress."
The attacking midfielder has had a fruitful spell for the Dutch outfit bagging 11 goals in 18 appearances, however his future at Vitesse seems uncertain.
When he was asked where he will be next season, he replied: "I don't know yet, it depends a lot on how we will end the season, it's hard to say now but I think we have a good chance of finishing in the top two and playing in the Champions League. But I'll go on my vacations, rest then we'll see."
