Giovinco was promoted to the first team during the 2006–07 season and also played his last season in the "Primavera" squad. His professional debut came on 12 May 2007, in the Serie B match against Bologna; he came on as a substitute in place of Raffaele Palladino, and marked his first appearance with an assist for David Trezeguet's tap-in. Since then, he had been tipped to be Alessandro Del Piero's heir in the creative number 10 role behind the main striker, known as the "trequartista", "rifinitore", or "fantasista", in Italian. Juventus won the Serie B title that season, earning promotion to Serie A the following season.
