This research analyses the effects of celebrity endorsement on consumer attitudes and decisions in the case of brands that are already prominent; it also explores the influence of fan identification on the effectiveness of endorsement. The aim is to identify whether brands of high status need celebrities, to trigger positive reactions. A confirmatory method is applied, using a questionnaire survey completed by 324 supporters of the Spanish football league. Brand recall, brand attitude and purchase intentions towards celebrity-endorsed sporting brands are analysed. We determine celebrities' differential effects on consumers versus endorsed brands, by calculating descriptive statistics and conducting multivariate analyses. Although previous research indicated that celebrities improve fans' reactions, our findings suggest that brands, when prominent, do not appear to require the effect of the celebrity to boost the attitude of the fans and their purchase intentions.
