England supporters who set up camp in Russian cities and sing about World War II next summer will be putting safety of the nation’s entire travelling World Cup contingent at risk, the head of British football’s policing unit has told The Independent.

Assistant chief constable Mark Roberts, who led the overseas British force which helped investigate attacks on England fans by highly organised Russians gangs at last summer’s European Championships in France dismissed the notion that the ‘10 German bombers’ – which was sung again in Dortmund last week – was simply humour and said that Russians will not differentiate between nationalistic trouble-makers and ordinary supporters.

“You try telling a Russian hooligan that it’s banter,” said Mr Roberts. “I would not like to try and float that argument next summer. Many people in other countries find some of the behaviour we are seeing offensive. It's vile and it alienates other teams' fans.

England vs Lithuania player ratings Show all 13 1 /13 England vs Lithuania player ratings England vs Lithuania player ratings Joe Hart - 5 out of 10 Had absolutely nothing to do in the first-half, and yet still very nearly managed to fluff his lines. Haring off his line to punch a long pass clear, he was beaten to the ball by Nerijus Valskis and was relieved to see John Stones booting his header off the line. Getty Images England vs Lithuania player ratings Kyle Walker – 6 out of 10 Given license to press forward at every opportunity, Walker had a mixed first-half before growing into the game later on. He helped set up England's second goal with a good burst forward and almost set up Dele Alli for a third moments later. Getty Images England vs Lithuania player ratings John Stones – 7 out of 10 Has been increasingly impressive for Manchester City in recent weeks and continued his good form at Wembley. Like Keane he had very little work to do defensively but he was superb bringing the ball forward and starting England’s attacks. Incredibly, he barely misplaced a pass during the entire match. Getty Images England vs Lithuania player ratings Michael Keane - 6 out of 10 Had remarkably little to do in defence after a solid debut away to Germany on Wednesday night. Hit several inch-perfect diagonal passes. Looks like he belongs at this level. AFP/Getty Images England vs Lithuania player ratings Ryan Bertrand - 6 out of 10 Stationed so far forward that he often looked as if he was playing as a left-winger in a 4-3-3 system. Saw a lot of the ball in the first-half but occasionally wasteful in possession, and his final ball was often lacking. Unlikely to replace Danny Rose in Southgate’s staring XI when the Tottenham defender returns. Getty Images England vs Lithuania player ratings Eric Dier – 7 out of 10 Another assured display from England’s utility man. Showed great tactical awareness to regularly flit between a role in England’s defence and their midfield, and dealt confidently with Lithuania’s aerial threat. Very tidy with the ball at his feet. AFP/Getty Images England vs Lithuania player ratings Alex Oxlade-Chamberlain - 6 out of 10 An industrious performance, albeit not groundbreaking in any way. When Southgate named his starting XI it was assumed Oxlade-Chamberlain would be deployed out wide but instead he sat in central midfield alongside Eric Dier. Saw a well-struck long-shot nicely saved in the second-half. AFP/Getty Images England vs Lithuania player ratings Adam Lallana – 8 out of 10 Comfortably England’s best player. Ran confidently between the lines to draw out Lithuania’s deep defence and hit a number of impressive in-swinging crosses into the box to test their goalkeeper. Set up England’s second with a sublime flick into the path of Jamie Vardy. Getty Images England vs Lithuania player ratings Dele Alli – 6 out of 10 After an impressive display against Germany earlier in the week, Alli struggled to make much of an impression at Wembley. Was on the receiving end of some very rough treatment from Lithuania’s defenders and generally took a backseat as Sterling and Lallana impressed. AFP/Getty Images England vs Lithuania player ratings Raheem Sterling – 7 out of 10 Made a very bright start before fading in the second-half, where he was quickly replaced by Marcus Rashford. Created England’s goal by beating his man and hitting a superb low pass across the face of goal for Defoe to finish. Getty England vs Lithuania player ratings Jermain Defoe – 7 out of 10 Southgate took a gamble when he handed Defoe his first England call-up since 2013. Twenty minutes into this match and his decision was validated. Smashed home from close-range with confidence for his 20th international goal, and looked lively throughout. Getty Images England vs Lithuania player ratings Jamie Vardy - 6 out of 10 Replaced Jermain Defoe with half an hour left to play and did very well, linking up nicely with Alli and calmly finishing when played through by Lallana for England's second. Getty England vs Lithuania player ratings Marcus Rashford - 7 out of 10 Did exactly what you expect from a thirty minute Marcus Rashford cameo. Terrorised his marker, repeatedly cut inside and was desperately unlucky not to score, or assist a goal. Getty

“As well as causing offence, it makes it more dangerous for British fans. These supporters are making themselves and everyone else a target.”

In an initial preparatory visit to Moscow last month, Mr Roberts, head of the UK Football Policing Unit, found that there is a high level Russian commitment to make sure that the World Cup passes off without the kind of clashes and hooliganism which soured last summer’s finals in France.

Despite last summer’s Russian surface bluster, with the national team’s striker Artem Dzyuba claiming English fans were partly to blame for the attacks on them in Marseille, some police chiefs in Moscow were mortified by their compatriots' level of violence. The recent BBC2 documentary, Russia’s Hooligan Army, has not gone without notice in the host nation and many Russian ringleaders are likely to be taken out of action.

Yet officers in both England and Russia believe that there will be little chance of preventing reprisals if England fans repeat some of the behaviour witnessed again in Dortmund, including singing nationalistic songs, booing opposition national anthems, and acting like an occupying army.

“You can’t expect rival fans or police to differentiate between drunken actions and actions which cause offence,” said Mr Roberts. “It also affects the way local police deal with supporters en masse. Foreign police will react.”

Police are presently reviewing footage from Dortmund, where many fans who sang continuously for 15 minutes about the war while making plane gestures at the end of their anthem. British officers are ready to ask magistrates to issue banning orders if it can be demonstrated that disorder in the Westfalenstadion contributed to violence.

Under section 14b of the Football Spectators Act, an order can be issued if a fan is shown to “contribute to any violence or disorder in the UK or elsewhere.” More than 2,000 British supporters are currently under such orders.

The Independent’s reporting of last week’s nationalistic singing in Dortmund prompted a backlash from some supporters. “Not everyone was a beer-fuelled yob,” said one. “I didn’t do the mock aeroplanes, so get your facts right.”

Another stated: “The Germans understand the song quite well. They just don’t feel targeted by it. Different era. Different identity.” And another: “Get a life. It’s banter – you know the type ordinary working folk take part in on a regular basis.”

But opposition supporters do not see it that way and though violence of Marseille proportions may be reduced by fewer fans travelling to Russia, intelligence suggests that supporters in that country view English supporters as would-be ‘top dogs’ who must be taken down.

The Football Association chairman Greg Clarke last week condemned the singing in Germany, while the Football Supporters’ Federation (FSF) said that “little of the wit and imagination that goes into our club football songs is reflected at England games.” The FSF sees the risk of a regression to the grim days of the 1980s when the nation’s supporters were greeted by dogs and riot police when they arrived in opposition countries.
