England’s players are using a sports drink developed by the double Olympic triathlon champion Alistair Brownlee to help control their body temperatures at the World Cup.

The Football Association placed a large order of CoreCtrl, a new product from Brownlee’s sports nutrition company truefuels, before the tournament to take to the US. Refuelling and heat management has been a key part of Thomas Tuchel’s preparations for the World Cup, with players wearing cooling vests and palm-cooling devices during training in Kansas City.
