The first episode of Watford: Behind The Badge, filmed by NBC at the club and broadcast online via BBC Three this Thursday, gives an in-depth look at how the Hornets help players recover from injury.

The American broadcaster streamed the first of the four-part series in the United States last night, and proved the no-holds barred documentary promised.

It included a heated discussion between Stefano Okaka and Valon Behrami, the kind of exchange you would have been hard-pressed to find in the likes of Channel 5's Being Liverpool.

UK viewers can view the half-hour episode from Thursday evening via the BBC Three website, with the focus primarily on how the club's pioneering medical department has helped players including Sebastian Prodl, Christian Kabasele and Isaac Success in recent weeks.

It details the array of tailored methods the Hornets have at their disposal to speed recovery from injury, and specialist equipment including an anti-gravity treadmill and a full-body cyrotherapy chamber installed at the club's training ground last season.
