His spell in the Eredivisie ended in controversy, with the Brazilian being jettisoned back to London before the end of the season.
But Piazon insists: "It was a very good experience.
"I have played a lot of games, it was something very important to me at that moment. I think I've done well in the beginning. After February fell back a little, but when you look at the season in its totality, I think it went well for me."
He added: "The Eredivisie is a great competition. All teams are trying to play football and try to play forward. Every team wants the ball and wants to keep it on the ground."
