The towering defender has admitted that the Parma forward could cause him problems in Wednesday's game, and added Inter have to defend as a unit
The centre-back has struggled against smaller attackers in the past, and Ranocchia has stressed that the Nerazzurri have to defend as a team in order to keep the Italy international quiet.
"It's more difficult to play against him than against a tall player, but that is mainly because Giovinco has great technique. He's great at beating players, so you need help from your fellow defenders and the midfield. You need to play as a unit otherwise he can hurt you because he's quick and he's got great technique," Ranocchia was quoted as saying on the official Inter website.
"I've already played against him. Sometimes I've come out on top, on others he has. When you're on the pitch you need to adapt to every type of opponent. In Serie A you come across all sorts of attackers - tall, short, slight, well-built.
"On many occasions I've heard people say I can't play against players like Giovinco. But that's not the case, otherwise I'd stop playing, or I'd only play when our opponents had a tall, powerful frontman."
Wednesday's encounter kicks off at 20.45CET.
