Thomas Tuchel spent time in the United States last summer during the Club World Cup
England manager Thomas Tuchel says he may have his substitutes stay in the dressing room during matches at the World Cup next summer because of the risks posed by high temperatures.
Speaking on the eve of the World Cup draw in Washington DC, Tuchel told BBC Sport: "If this is what helps us later in matches when they come on, we have to consider it a possibility.
"Nobody likes it because I want the players to be out there to feel the energy and give us energy from the bench on to the field.
"But I saw players doing this at the Club World Cup. Hopefully we can avoid it. It's always better when they can be with us outside."
