Defender Allan Nyom has left Watford to sign permanently at West Brom, the club has confirmed.

Nyom only signed a new four-year deal with the Hornets at the start of the month, but has now departed Vicarage Road for the West Midlands in a deal believed to be worth around £3million.

The Cameroonian international made 32 Premier League appearances in his debut season with Watford last year, but has featured only once for the Hornets this campaign, in their 2-1 League Cup defeat to Gillingham last week.
