Suso admits former Liverpool teammate Mario Balotelli convinced him about moving to AC Milan.
The midfielder joined the Rossoneri over the weekend.
Suso said: "I've known about the transfer for six months, so I was able to speak with him about it, and he said very good things about the club.
"I've already spoken with [Coach Filippo] Inzaghi when I had my medicals and he made me feel at home. He was one of my idols as a player."
