The Dutchman has hailed the Italian striker's talents after rumours linked him with a move back to Serie A, while also insisting he is happy at San Siro after settling in
The Italy international has struggled to hold down a place in Roberto Mancini's side this season, and is also interesting Ligue 1 giants Paris Saint-Germain.
Despite a disappointing campaign so far, one bright spot for the Rossoneri has been Stephan El Shaarawy, with the 20-year-old leading the Serie A scoring charts, but De Jong believes the two Italian strikers are not comparable.

"It is difficult to make comparisons, everyone has his own talent and his features. Stephan is currently one of the biggest in the world, he is playing at the highest level and he is just 20.
"You don't have to be crazy, and he isn't, to be a great player. Balo [Balotelli] is great but he must feel good to do his best."
The Netherlands international admitted that he initially found it hard to adapt to life in Italy, but maintains he is happy to stay, but took a swipe at Italian supporters after playing in stadiums with few fans in.
"It took me longer than I expected to settle here but I've only been here for two months," De Jong added.
"Every game I try to do better. Everything is new for me here, the coach is looking for the best game plan and I have to adapt. Recent results show that we are on the right track with the 4-3-3.
"I like Italian football even if the stadiums are empty."
