The England camp is fully aware of the challenges that conditions at FIFA’s next global gathering could pose. It is claimed that at least four cities could exceed the 32 degrees Celsius mark that triggers automatic cooling breaks.
Research led by Queen's University Belfast has pointed out that 14 of the 16 stadiums scheduled to host World Cup fixtures could reach the “potentially dangerous” mark of 28 degrees Celsius.
Three Lions boss Thomas Tuchel has already said of potentially soaring temperatures, having experienced them first hand during his time in charge of Chelsea: "It is important to see matches now in America, and in Miami at three in the afternoon. The actual experience is for the players, but I have done pre-season there in Orlando and I will be very surprised if we do not suffer. Suffering is one of the headlines for this World Cup."
