The creative midfielder was one of the undisputed stars of the Inter team that won the treble in 2009-10, but was then frozen out after refusing to accept a pay cut.
Sneijder eventually left Inter for Galatasaray in Jan. 2013, yet he has not forgotten how some people at board level within the San Siro side treated him.

"I've been thinking about my time at Inter and I realized that the team that won the treble has been dissolved within a matter of seasons," the Netherlands international told La Gazzetta dello Sport. "Inter did not treat me well, but that was the work of certain directors. I love Inter and I want them to do well, also for the fans. I really do hope that Inter can win the Scudetto.
"Juventus have won a lot in Italy and Roma are on the rise. The teams from Milan had gotten used to success, but things are a bit difficult for them now."
Sneijder then went on to voice his admiration for former coach Jose Mourinho and stressed that the Chelsea boss remains a special person for him, even refusing to rule out a future move to Stamford Bridge.
"Mourinho is the number one. There is no one like him," he added. "I'd never say never no to Chelsea, but fact is that I am very happy in Turkey."
The playmaker, 30, has a contract with Galatasaray until June 2016.
