Doping concerns in rugby

Players have become faster and stronger, prompting concerns about use of illegal means to get there.

The 2015 Rugby World Cup takes place in England later this year.

New Zealand will be defending the title they won by beating France four years ago.

But 20 years after the sport went professional, players are stronger and faster than ever before.

It has led to questions in France whether illegal means are being used to achieve that.
