English Grammar for Spanish speakers

I believe it can be helpful to learn English grammar in your own language.
I learnt Spanish in secondary school and my teacher was English.
However we had Spanish oral classes with a native Spanish speaker.


There are quite a few English grammar books written in Spanish but the one that has been recommended to me by Spanish teachers of English is 
'Gramática Inglesa' by Francisco Sánchez Benedito.

I have recently bought this book to use in my classes.
