Yara, it's more natural to say "which team do you support....?" rather than "encourage". In answer to you question, I support West Ham United.

Atletico Madrid. :-)

Sofia, no! It's Real Madrid all the way!

Benfica. In Spain between these two, I prefer Barça, but in Spain, I support the Atl. Madrid. In Germany BVB, in England Liverpool. But I think the number one in my heart will always be Benfica. It's the only one that I go to the championship parties, but I have scarves from all of them. 

Real Madrid! I have been indoctrinated by a Spanish student.
