Bank Vole

This looks like a vole to me. Can't give you much more than that though... no clue what species of European vole there are other than Bank Vole (and Water Vole?)

This is a Bank vole.

@Great Argus It is great you want to help, but if you have no clue about what species it could possibly be, it is not very helpful.... E.g. there are no Deer mouse in Europe and there are 7-8 species of Vole in the Netherlands (depending on taxonomy).

Thank you very much lintworm !

I believe this is a field vole (microtus agrestis)

Definitely Bank Vole (Myodes glareolus).

After a second look, I agree with @Maguari
