England's players were left frustrated at being denied water breaks during Sunday's 1-0 win over Croatia, a game played in stifling conditions that left many of them gasping for breath.
Tyrone Mings said it was the hottest match he had ever played in, and Gareth Southgate responded by taking the unusual step of withdrawing a seemingly fatigued Harry Kane, one of three substitutions made by the England manager.
The majority of Southgate's squad became accustomed to water breaks when playing in high temperatures last summer after they were introduced by the Premier League for Project Restart, an attempt to combat the increased likelihood of injury and fatigue.
