The Baggies were backed by a 2,000-strong army of supporters in South Wales after the Club subsidised ticket prices for the Liberty Stadium trip.
And many of them came bearing Spain flags to help spur Madrid-born boss Mel onto the first win of his Hawthorns reign.
“If the players win or lose I only help them,” he told the WBA website.
“The fans are important too because they are always with us.
“I saw the Spain flags in the away end and this win is for the fans who have been very, very kind to me since I arrived at the club.
“I have a responsibility to them for the future.”
