The Football League has signed Umbro Isotonic as the official sports drink for the new season, which kicked off last week.

The £250,000 deal means the energy drink, produced by Calypso Soft Drinks, will be used by players and officials of about 50 football clubs that make up the first, second and third divisions.

It is also the official drink for all nationwide Football League games and two cup competitions and will also sponsor the Youth Alliance for under-17 and under-19 teams from all clubs in the Premier, Football and Conference leagues. The orange and citrus
flavours in 50cl PET bottles contain glucose, maltodextrin and vitamins designed to help athletes perform more effectively.
