Cape Town - Kieran Gibbs is due for a medical at West Bromwhich Albion after they agreed a fee with Arsenal for the left-back's services.
The 27-year-old was also a target for Watford, but their interest came to an end on Tuesday due to a disagreement over personal terms.
Gibbs has been deemed surplus to requirement at the Emirates Stadium this season following the arrival of former Schalke defender Sead Kolasinac.
The Gunners youth product's influence has waned over the past two campaigns after losing his place in the first team to Nacho Monreal, and he was absent from the squad that travelled to the Far East for their pre-season tour last month.
The north Londoners have decided to cash in on Gibbs, who is in the final year of his contract, with reports suggesting the Baggies will pay £7 million for his signature.
