Or can you? Scotland's Under-21 team were the latest to defy Alan Hansen's infamous claim as one of their callower line-ups, featuring a 17-year-old and an 18-year-old in central defence, overcame Slovakia to leapfrog their visitors and move into second place in qualifying Group 3 for the 2015 European Championship finals in the Czech Republic.
For all that this was a triumph for youth, the goals which made the difference came from two of the more senior members of the party.
Captain Stuart Armstrong, 21, of Dundee United - a man who has graced the full squad - got things started with a fine left-foot finish, before a first goal in Scotland colours on his debut at this level from Stevie May gave the hosts a lead which they never surrendered.
A delighted Billy Stark said he felt his players had risen to the challenge following successive heavy defeats by England and the Netherlands, while May in particular passed his audition in front of the watching Gordon Strachan and the entire full squad. "They have had a wee bit of criticism which was absolutely on the money in terms of the England game but we were able to draw a lot from the Holland game," said Stark. "We had something to prove and that is a good situation to be in. With young centre-backs particularly, and a lot of the boys eligible for the next campaign again, you have got to be delighted. Stevie got his opportunity and grabbed it."
Slovakia had brought a mainly home-based squad, notable exceptions being captain Norbert Gyomber of Catania, Stanislav Lobotka on the books at Ajax, Portugal-based playmaker Jakub Vojtus and striker Milan Lalkovic, from that other hub of the world game - Walsall.
Teenagers Jordan McGhee of Hearts and Celtic's Stuart Findlay comprised the central defence, while there were first starts at this level for Lewis Macleod of Rangers, Callum McGregor, on loan at Notts County from Celtic, and May.
The Scots made a vibrant start, with McGregor - the scorer of six goals in his 12 appearances to date in Nottingham - showing why with two fine efforts, both with his supposedly inferior left foot. First he had a shot saved by Patrik Le Giang, following fine work from Ryan Jack and May down the right, then he burst into space on the opposite flank before firing narrowly over.
Ironically, just as the visitors appeared to be recovering and penning their hosts in - Jakub Paur had a drive saved by Jordan Archer - Scotland assembled a two-goal lead. Armstrong showed great technique to guide in a low cross from Clark Robertson, then May outmanoeuvred his man before scoring with a high finish, from his supposedly weaker foot.
May is the top-scoring Scot in the SPFL Premiership and he could have had more here: he rounded Le Giang only to have his cross shot blocked, before Fraser Fyvie was similarly wasteful having eliminated the goalkeeper just minutes into the second period.
The architect of that chance, as so much on the night, was Celtic's Dylan McGeouch, and from another fine McGeouch cross, May's glancing header rebounded from the junction of post and bar. The St Johnstone striker then turned provider to set up McGregor, although Le Giang was equal to his attempt.
The Slovaks had introduced winger Jaroslav Mihalik and 6'6" target man Thomas Malec at half-time and, after one near miss between the pair of them, Malec converted Mihalik's cross to bring the Slovaks back into the game. They almost had parity too, when Archer misjudged a corner, Paur won the header and Fyvie had to look sharp to karate kick the ball clear from underneath his own bar.
The Tottenham Hotspur goalkeeper just about recovered his poise from a few late set plays, and got his reward after a late onslaught when the final whistle gave the Scots three points.
Fyvie and McGhee were grateful that the Croatian referee opted to leave his red card in his pocket for a couple of reckless challenges, but Scotland breathe again, moving on to a meeting in Tbilisi on Monday with Georgia, beaten 6-0 yesterday by the Netherlands.
