Former world champions England are said to have built a ring of steel at their training base in Russia so as to protect them from being watched by opposing spies.
The English team known as the Three Lions will train at Stadium Spartak Zelenogorsk which is six miles away from their Repino base at the forRestMix Club hotel.
The small stadium according to the report by UK Sun is usually used for local tournaments and has a six-foot high wall surrounding its perimeter.
But England chiefs have reportedly ordered the height to be increased to 13 feet so that they can keep their tactics out of view from opponents and the media.
England are in Group G at the 2018 FIFA World Cup where they will face Tunisia, Panama and Belgium for a fight to make it to the knock out stages.
