Hi
@Rotem17, welcome to the Community

Unfortunately when it comes to regulated markets (.de, .ro etc) The settings of the language can't be changed. One of the points when receiving a license on a market is that the site needs to be in the language for the country. What can be done in this case is using Chrome's automatic translation tool, however there might be mistakes, when it comes to reading Terms and Conditions of important info provided, there is a risk of misinterpretation. Hope this helps.
