A day after the Swiss national side got booed off the pitch in Geneva after losing 1-0 in a friendly to Norway, the teenagers kept their composure and won their seventh game in a row thanks to Haris Seferovic's header in the 63rd minute.

The Swiss started tensely however. Their opponents, spurred on by a packed stadium of 64,000 fans, turned on the pressure right from the whistle and the first quarter of an hour saw some frantic defending by the Swiss.

Swiss coach Dany Ryser got a scare after less than ten minutes when his goalkeeper Benjamin Siegrist ñ who has played a large role in getting the team to the final ñ took a boot to the head and was down for several minutes.

Siegrist recovered and the Swiss eventually settled and found their rhythm.

Both sides had a couple of chances ñ plus a few wild shots at goal ñ although neither team missed any sitters. 0-0 was a fair score at half-time.

The Swiss started the second half the better team and had two good chances within ten minutes.

It was third time lucky, when in the 63rd minute Haris Seferovic found himself on the end of a long corner and guided his header past the Nigerian keeper, silencing the home fans. Good goal!

This was a deserved lead for the Swiss, but how would they ñ and indeed their opponents ñ react? Push for a second or go on the defensive?

As it turned out, both sides upped their game and created chances. This was a high-quality, exciting and entertaining match ñ adjectives that, it has to be said, can rarely be applied when Switzerland play.

World champions!

And then in the 78th minute the Nigerians scored. Or at least they thought they had ñ and television replays of the resulting goalmouth melee, although not conclusive, certainly seemed to back their case.

But the goal wasn't given ñ Swiss keeper Siegrist once again excelling himself ñ and Switzerland just needed to hang on for another 11 minutes.

Most of the rest of the match was spent in the Swiss half, but the Nigerians couldn't break the solid defence.

Peep! Peep! It's all over! Switzerland have held on and are world champions! After victories against teams including Brazil, Germany, Italy and Colombia, Switzerland ñ population 7.7 million ñ has beaten a country 20 times its size to become world champions!

This was an excellent, mature performance and a fully deserved result - the Swiss commentator compared it to Roger Federer's first Wimbledon title.

While the U17's success bodes very well for the future, a more immediate ñ and admittedly pointless ñ thought was whether the U17 squad could beat the national team. A majority of swissinfo.ch readers thinks it could.

For what it's worth, earlier in the day Spain beat Colombia 1-0 to claim third place.
