The left-footed central defender was born on February 20, 2002 and comes from Salernitana, with whom he has played as a starter for the last two years in Serie A. He started in the infrastructure divisions of Inter, with the first team of which he made his debut in the Italian Championship in 2020. This was followed by a two-year loan spell at Monza, which saw them gain promotion to Serie A. In Serie A, he has made 54 appearances and scored three goals.

Referring to how he made the decision to continue in Greece, Pirola said: "Olympiakos is definitely the most important club in Greece, they recently won the Conference League so this year they have a chance to make a good run in the Europa League. It was an easy and quick decision for me to accept the offer, and I'm sure I did the right thing by coming here to play."
