Bundesliga side Werder Bremen announced Tuesday they have shelved plans to tour Indonesia next month because of an on-going row between the Indonesian FA (PSSI) and the country's government.

A disagreement over the new Indonesian Super League season has put the competition in jeopardy with football's governing-body FIFA threatening sanctions if the government keeps interfering.

Bremen, who are challenging for a Europa League place for next season, had planned friendlies in the south-east Asian country at the end of May, but say the situation is now too complicated.

"We were very advanced in our planning, but under these conditions there are too many questions which have been raised and there are too many question marks," said Werder's Chief Executive Officer Klaus Filbry.

"Internationally, we want to show ourselves at our best, but it won't be possible this time.

"So in this respect, we have changed our plans at short notice."

Bremen say they are now planning three friendlies at the end of May with exact dates and opponents set to be announced.
