Speaking afterwards he struggled to contain his delight.
"It was good for me, it was special, to score in my second game," said the forward. "The debut in Seattle was special too but this one was even more so I am very happy.
"It was a nice goal, made in Brazil! Rami and me try to do this in training so it was really good to achieve it."
Piazon has fitted well into first-team surroundings, having trained with the senior players at Cobham, and appears unfazed by the attention that a Chelsea tour brings. He believes having many familiar faces around him has helped.
"It is good to have people around me, friends from Brazil and youngsters from the youth team, so I feel fine and it's a very nice trip for me," he told chelseafc.com.
"On the pitch it is another level, it is really hard but I know that with time when you play and play and play things get better and step by step you grow as a player, so we will see what will happen."
