A It varies each year: football clubs change kit sponsors on a regular basis. That said, Adidas have signed some longterm outfitter deals: 10 year deals with Manchester United and Bayern Munich. For the 2015/2016 season, the following football clubs wore an Adidas football kit: Aberdeen, AC Milan, Ajax, Anderlecht, Bayern Munich, Benfica, Besiktas, Chelsea, Emelec, Manchester United, Juventus, Feyenoord, Fenerbahce, Flamengo, FC Goa, FC Pune City, Fluminense, Lyon, Marseille, Melbourne Victory, Nottingham Forest, Olympique De Marseille, Palmeiras, Partizan Belgrade, River Plate, Real Madrid, Real Sociedad, Schalke 04, Sunderland, Swansea City, Universidad de Chile. Adidas also signed a longterm outfitting deal with the MLS (Major League Soccer) in the United States; therefore, every club in the MLS currently wears an Adidas kit. While the above list of clubs is far from comprehensive, it gives a good insight into the major clubs that Adidas outfit. Real Madrid are the most successful club in Spain, Manchester United are the most successful club in England, Bayern Munich are the most successful club in Germany, and Juventus are the most successful club in Italy. While Adidas have not managed to outfit all the top clubs in Europe - Nike outfit FC Barcelona and NB outfit Liverpool - they do have the most prestigious list of clubs of any sportswear outfitter.
