Before his move to Genoa, Simeone played for the Argentinian side River Plate. His first season for the Italian team was very promising, but during the 2015-16 campaign he was loaned to the Argentinian club Banfield, where he scored 12 goals in 31 appearances.
Last season, Simeone scored 12 goals in 35 appearances for Genoa, showed his delight at receiving the chance to play for Fiorentina, with whom he signed a five-year contract.
“I am happy and I know I have to give my all. This is a wonderful opportunity for me", the 22-year old told Fiorentina's website.
Diego Simeone is obviously proud of his son, but he also said that he will not consider bringing him to Atletico.
"Thinking about seeing him in one of my teams would mean giving him a responsibility that wouldn't be good for him. Giovanni has qualities that I like a lot and with effort and hard work he will definitely become a big player, but not with my team", Diego Simeone said.
