I'm Spanish, and the title not sounding natural to native English speakers is something that happens very often when writing in a language that you only learned at an older age. 

Keep in mind that living in an environment surrounded by a different language than the one you artificially try to communicate on comes with such disadvantage, because the grammar structures are not the same and, yet, your brain unconsciously tries to apply them because it is what it feels right or natural to do, even if it isn't.

PD: El País is a Spanish newspaper.
