England football team spend 48 hours with the Royal Marines - and it does not look fun
The England squad experienced a different kind of boot camp last weekend after manager Gareth Southgate arranged a top-secret trip to the Royal Marines' Commando Training Centre.
Twenty members of the England squad, along with key members of the English FA's backroom staff, were whisked away on a surprise trip to the base in Devon and spent 48 hours in army fatigues completing a series of exercises designed for marine recruits.
They included a night of camping under the stars on Woodbury Common and pictures carried on The FA's official website show Southgate was not afraid to get involved.
In one of the images the Three Lions boss is seen being helped out of what looks to be a water hazard of an obstacle course.
Elsewhere, Raheem Sterling is pictured preparing sleeping bags in darkness and Jake Livermore is applying camouflage paint.
The players will reconvene today at St George's Park, joined by Gary Cahill, Eric Dier, Chris Smalling, Jesse Lingard and Marcus Rashford - who missed the excursion - to prepare for Saturday's World Cup qualifier against Scotland in more familiar surroundings.
"We wanted to put the guys into a different environment, something they weren't expecting," said Southgate.
"The Marines talk about a dislocated expectation, and that was part of the theme of the camp - how will we be adaptable in moments of difficulty for us as a team?
"There were some team objectives around pushing themselves beyond where they thought they could go and knowing you don't want to let any of your team-mates down.
"We wanted to expose the guys to an elite environment with one of the elite forces in the world. We wanted them to see that there's another world out there."
Meanwhile, Scotland's players turned up at their training base on the outskirts of Glasgow in various levels of fitness.
Left-back Kieran Tierney is having a gum shield made for the game following his mouth injury, which meant he trained alone for the most part.
Striker Leigh Griffiths was not feeling well, while midfielder Darren Fletcher also missed out after playing in the Michael Carrick testimonial last Sunday.
However, manager Gordon Strachan was given a lift by the attitude of the other players who reported for duty after a long domestic season.
He said: "As a coach, you are meant to inspire players, but the players inspired the whole coaching staff. Their attitude was absolutely phenomenal."
