England’s footballers could be forced to cope with a dramatic rise in temperature when they transfer from their World Cup training base to Volgograd for their opening game.

Gareth Southgate’s squad on Tuesday head to Repino, close to the Finnish border, with the temperature expected to be as low as 15°C for their first training session on Wednesday.

But they then travel more than 1,000 miles south to Volgograd for their first group game against Tunisia on Monday with the mercury expected to rise as high as 33°C there by the end of this week.

A more southerly training base in Sochi had been considered by the FA but Southgate thought it too hot when he visited the city that hosted the 2014 Winter Olympics. Instead, the England manager opted for Repino after a pre-tournament build-up at St George’s Park. 

And while the unusually warm temperatures here in the UK will have assisted England’s players in becoming acclimatised, Volgograd could present a major challenge. It could even be significantly hotter by the time they meet their north African opposition.

According to sources, Southgate and his staff are unconcerned and believe this England side is good enough to dictate the pace of the game against Tunisia.
