Financial details were not disclosed but media reports said Barca agreed a €40 million (US$44.07 million) fee with €21 million in add-ons for the player seen as the successor to Robert Lewandowski who turns 35 next month.

The 18-year-old has scored 22 goals for Paranaense in 66 appearances, helping them reach the Copa Libertadores final last season.

He earned his first cap for Brazil in March, becoming the youngest ever debutant for the five-time world champions.

“In footballing terms, a centre forward still in development, but his adaptability means he can also play on the wing should the situation require,” Barcelona said in a statement.

“An excellent reader of the game, he also stands out for his pace and his finishing skills in front of goal.”

Barcelona said they have inserted a buyout clause of €500 million into his contract.
