Now, according to IQUII Sport's European Football Club Report, Nike are the most popular manufacturer across the 237 clubs involved, boasting deals with 15.61% of teams.
Next up on the list was Adidas, who represent 10.97% of the 237 sides. Manchester United's £750m deal with Adidas is the most lucrative in the world when it comes to value-per-season, whilst they recently added Arsenal to their clientele.
Italian sportswear giants Macron make it into third with 9.7%, largely due to their dominance in the Serie A.
Macron have deals with Lazio, Bologna, Udinese, Cagliari and SPAL, whilst they also boast numerous deals in Portugal and Spain. In La Liga, they work with Deportivo La Coruña, Levante and Real Sociedad, as well as plenty of sides from the second tier.
Puma, Kappa and Umbro all boast over 5% of the sides, but the biggest surprise in the top ten comes in the form of Portuguese company Lacatoni, who are immensely popular in the Portuguese Primeira Liga.
