The Holland midfielder flirted with United during the World Cup, admitting he had ambition to one day play for the Red Devils.
Sneijder's long-term future now appears in doubt after his representative Soren Lerby declared Inter had 'broken their promise'.
"Financially we can't work out a deal. Negotiations have been pulled off and will only be restarted if Inter will show an opening," Lerby told Dutch newspaper De Telegraaf.
"Wesley was contacted by clubs across Europe after the World Cup final, but he was very happy in Italy at Inter.
"He felt he couldn't leave the club after just one season and the very flattering words of owner Massimo Moratti, who stated he would be the leader for the coming years.
"Wesley would get a fantastic wage and he would get a clause with a high transfer fee. Unfortunately Inter couldn't keep their promise."
