Well that mystery has been solved as Inter have now announced he will wear jersey number 96, representing the year of his birth.
After making his Santos debut as a substitute in Neymar’s final match before departing for Barcelona in 2013, Gabriel scored 57 times in 157 appearances in all competitions, winning two Campeonato Paulistas with the club.
He scored on his Brazil debut in the 2-0 win over Panama in March and has now struck twice in four games for the national side.
The youngster also represented his country at the Copa America Centenario and played an important role in securing Olympic gold at Rio 2016.
Now he has set his sights on performing for Inter.
“Becoming an Inter player on my 20th birthday was a wonderful present,” he said. “It feels amazing to join a club with so much history.
“I’ve already had a taste of the Nerazzurri supporters’ passion and I can’t wait to play in front of them at San Siro. It is a dream come true.”
