West Brom have signed full-back Allan Nyom from fellow Premier League side Watford for an undisclosed fee.
The 28-year-old has signed a four-year deal at The Hawthorns and replaces Cristian Gamboa, who joined Celtic.
The Cameroon international joined the Hornets last summer, making 36 appearances in all competitions.
He becomes Tony Pulis's third signing of the transfer window after bringing in winger Matt Phillips from QPR and defender Brendan Galloway from Everton.
