You would be forgiven for listing the likes of Germany, France and Spain, as the teams that will be prepared and equipped to cause England's down fall at the European Championships in France this summer. However, Roy Hodgson's first big test will not come in the form of one of Europe's elite.
It was 1958 the last time Wales qualified for a major tournament, but they are not in France to be a part of the event, but to cause upset along the way. And on that joyful night in Bosnia last October, it was destined that The Dragons would be placed in the same group as England.
The two British sides will meet at Stade Bollaert-Delelis next Thursday, looking to not only steal the local bragging rights, but gain three precious points towards the knockout stages. And Hodgson will be well aware the Chris Coleman's squad have all the inside knowledge in order to plot the Three Lions' downfall.

Yes, England have been handed a relatively generous group, when you consider the likes of Belgium, Italy, Sweden and the Republic of Ireland make up Group E. But Hodgson will not be taking the group stages lightly; especially with the quality and expertise that Wales possess.
Neither Russia or Slovakia can boast the experience that the Wales' squad can, when it comes to facing this England squad. However, 12 of the Welsh team have come up against England's men, playing in the Premier League, this season.
Danny Ward and Joe Allen know too well about the quality of their Liverpool teammates Nathaniel Clyne, Jordan Henderson, James Milner, Adam Lallana and Daniel Sturridge. Allen will, no doubt, giving Ben Davies plenty of advice on how to keep Clyne quiet, when he come face-to-face with the right-back. While Ward will be able to give tips to the Wales defence on how to keep Sturridge quiet.
Davies, too, will be able to offer his team plenty offer his teammates; having spent this season playing alongside much of the England squad that will likely start against Russia on Saturday.
Having been challenging Danny Rose for the left-back role at Spurs - while also featuring alongside Kyle Walker, Dele Alli, Eric Dier and Harry Kane - Davies will have plenty to say about his Tottenham teammates to Coleman, ahead of their eagerly anticipated meeting.
However, Leicester's Andy King, despite the undoubted affection he will have for Jamie Vardy - with the England striker having played a leading role in The Fox's magnificent title winning campaign - will be giving his Wales teammates all the tips he can, to keep the England frontman quiet.
Ironically, the one man who lacks much experience against England's players in the past few seasons, is star man, Gareth Bale - now plying is trade in La Liga - but he will not need any reminding of what it takes to compete against the best in England.
It is certain that Wales will be the best equipped side to face England in the group stages: Russia will have no representatives from the Premier League at this year's tournament, while Martin Skrtel will be the only one who can offer Jan Kozak any advice on how best to quash England's attacking threats.
But it won't simply be the fountain of knowledge Wales' players possess about England's squad that can upset the Three Lions, it will be quality also.
James Collins has been a part of a successful campaign for West Ham, while Ashley Williams name is often linked with bigger and better clubs than Swansea; having performed admirably in the Premier League.
Allen has made a name for himself as an impact substitute at Liverpool this season, while King guided Leicester to an historic league title. And that's not to mention Wales' top two players; Aaron Ramsey and Bale.
Perhaps it's of benefit to England, also, that all but one of Wales' squad plays in Britain. While Slovakia and Russia will not know what to expect of the likes of lesser names like Allen, Williams, Davies and Joe Ledley. Hodgson will know all too well about the quality within this generation of Welsh talent.
And while most of Europe may not take Wales seriously, if there is one team that can give Hodgson a sleepless night at this phase of the tournament, it will be Coleman's Dragons.
