The international right-back joined the Premier League club earlier this year but after being denied a UK work permit, he was sent on loan to Switzerland along with Teerasil Dangda.
''It is difficult for me to improve because the standards of the reserve side are similar to that of a third division club in Thailand,'' Suree told the Bangkok Post.
''I don't know anything about my future. Teerasil and I are very lonely because our apartment is far from the city.''
Suree is heading back to Thailand to join City's Asian tour and will then be in action for the national team against Bahrain in a 2010 World Cup qualifier on June 2.
''After that I will stay in Thailand for a while to hear from City whether they want him to go back to Zurich or loan me to a club in Australia or China,'' he said.
''I am ready to play anywhere until the contract with City expires because they pay me a monthly salary which is quite a large amount.''
