And he insists life under his old Light Blues gaffer Walter Smith was the perfect preparation for the Premiership.
Gattuso told the Scottish Sun: "Playing under Walter made a big impression on me. It was a good time and I have a lot to thank Rangers for.
"The thing I remember most is the atmosphere. I enjoyed my time in Scotland because of that."
He continued: "I like the Premier League. It is the best league for me and for my characteristics.
"I like Scotland and England and I like the fact that when you finish playing the game it's finished.
"In Italy it's not the same because there the game isn't finished after 90 minutes. Not even after one day, two days, three days. If a referee makes a wrong decision we speak too much."
