The Spaniard left Anfield in January 15 after he has struggled to impress the club managers since 2011
After an unsuccessful four-and-a-half years at Liverpool Suso managed a 21 first team appearances.
The former Liverpool midfielder has been impressive for Milan since his low-key arrival for £1m, helping the Rossoneri to the Coppa Italia final while the appointment of Gennaro Gattuso as head coach has resulted in an upturn in Serie A results.
"Premier League football is different, I would call it special: I would like to play for Liverpool again someday. I grew up there and it is a big club," Suso told the Observer.
"I'm very happy at Milan. Always when there are rumours about me leaving I reiterate that I am happy here and I think the club is with me.
"I have a release clause and that was something both the club and my agent wanted. If the club wants to continue to be among the top sides and count on me then I am here for them."
Suso also spoke about his experience during his time at England.
"In a sense I became a man before I became a footballer,' he added. It was very hard with the lifestyle and language.
"But to this day I remember everything. I did not play that much but I got to know Steven Gerrard and be a team-mate of players such as Luis Súarez, Philippe Coutinho and Jamie Carragher. I'll never forget my experience at Liverpool."
