Giovanni Silva de Oliveira, Brazilian footballer and manager
Giovanni Silva de Oliveira (born 4 February 1972), better known as Giovanni, is a Brazilian football manager and former player. A versatile playmaker, his natural and favorite position was as an attacking midfielder, but he could also play as a forward, being an exceptional goalscorer. He was predominantly known for his world-class technique, his exceptional dribbling skills, and his outstanding flair and creativity on the ball, which saw him employ a variety of crafty moves, as well as his passing accuracy and goalscoring ability. At club level, he most notably played for Spanish side Barcelona, Greek side Olympiacos, and Brazilian club Santos. Internationally, he played for the Brazilian national team, gaining 20 caps and scoring 6 goals; he was part of the Brazilian team that reached the 1998 FIFA World Cup Final.

In his prime, Giovanni was one of Barcelona's most valuable players, but after the arrival of Louis van Gaal at the club, he got into conflict with the Dutch manager, along with fellow Brazilians Rivaldo (whom van Gaal wanted to use as a left winger, despite his protests) and Sonny Anderson. He famously called van Gaal "a Hitler for Brazilians, and an egomaniac". At Olympiacos Giovanni had the happiest and most successful days of his career, and is still remembered as a club legend by supporters.
