Mainz midfielder Julian Baumgartlinger insists he's not made any decision over his next move.

The Austria international is off contract in June and is being linked with West Ham United this week.

"I have no stress, I feel very well and I do not need to rush into a decision," said Baumgartlinger.

"It is normal that rumors arrive, but I am concerned only with concrete things."

Of the Hammers interest, the midfielder added: "The focus is more on Germany. This is the most balanced, perhaps even the strongest league in Europe."
