What is the biggest concern for a Navy veteran , with no formal managerial experience , preparing to lead another country 's team out in front of 30,000 of his baying compatriots ? 'Suit or tracksuit ? ' jokes Gibraltar 's interim head coach Davie Wilson , who will attempt to guide UEFA 's newest member to an historic result at Hampden Park on Sunday . He adds : 'Growing up in Scotland , it 's a boyhood dream to step out at Hampden for your country . But to step out for another country against your own country… I 'm totally mixed with emotions . Davie Wilson ( centre ) was born in Scotland but is the current Gibraltar interim head coach . ' I 'm massively humbled , yet there 's a little devil on my other shoulder saying , 'What are you doing ? People might never speak to you again ' . ' But the 41-year-old freely admits it would take a very poor performance from Gordon Strachan 's men for his charges to leave Glasgow with anything more than pride . Wilson , part-time head coach , part-time exercise rehabilitation officer , was on the books at Kilmarnock during his teens , but decided the Navy offered a more realistic opportunity . After two decades at sea , Gibraltar was to be his final port of call , and he has an obvious fondness for the British territory . ' I miss the Scottish scenery but where I am now ticks the boxes , ' he says . 'After 21 years travelling the world , I 've found somewhere I feel is home . ' The former assistant head coach , who was handed the reins just three weeks ago , is enjoying every minute of his adventure but the national anthems will throw up an unusual dilemma . 'How do you stop a Scotsman singing Flower of Scotland ? You ca n't , ' he admits . 'If it was New Year 's Eve I 'd be on the table singing it like I meant it ! At Hampden I 'll be singing it , but I do n't have to show that passion . Scotland are heavy favourites for the clash and will be expecting to vastly improve their goal difference . ' I 'll be passionate during the Gibraltar national anthem . I 've sung it every game for the last two and a half years and I 've felt the hairs rise on my arm . On Sunday I 'll feel the hairs rise for both anthems . 'Gibraltarians are close to the Scots in terms of being passionate about who they are . As a nation , Scotland feel they 're not given the freedom they deserve , Gibraltar is the same . ' The debutant manager must prepare his squad with only three professional footballers . Their occupations range from policemen and firemen to solicitors and customs officers . How must Wilson have felt when his team lined up against the Germans in Nuremberg last November ? He says : 'As world champions , they were expected to trounce us . I listened to Alan McInally 's commentary and , when Thomas Muller scored the first goal , he said , ' I 'm fully expecting the Germans to put on a cricket score tonight ' . But they did n't . ( They won 4-0 ) . You could see it in their manager 's face when we had a shot at goal , and a second shot at goal and a corner . He was angry . Scotland duo Christophe Berra ( right ) and Craig Forsyth train ahead of their side 's forthcoming clash . 'We 've got to build for the next 10 or 20 years . We wo n't find a Lionel Messi in a country of 30,000 — there will be more people in the crowd on Sunday than in our entire country . ' Wilson would clearly relish the chance to oversee Gibraltar 's development on a permanent basis . 'It 's starting to sit better on my shoulders , ' he says . ' I feel confident in my ability and now I 'm thinking , 'why not me ? ' . If I was offered the job I 'd bite their hand off . ' But whatever happens , Wilson will always have his place in history . 'Not even you journalists could have written this story , ' he says . 'If nothing happens after Sunday 's game I 'll always have this memory . ' I 'll tell my grandkids , 'You know , your grandad managed a football team once ' . They 'd laugh — 'Of course you did grandad . Now tell us another Navy story . '
