West Brom are interested in signing Kieran Gibbs and have approached Arsenal to discuss a potential transfer, Sky sources understand.
Sky Sports News HQ has been told the Gunners want around £10m for the defender, but Albion are not prepared to pay that amount.
Baggies boss Tony Pulis, who is currently with his squad in Hong Kong for the Asia Trophy, has been looking for a specialist left-back and sees Gibbs as his best option.
The 27-year-old made just eight Premier League starts last season and 22 appearances in all competitions overall - his second season struggling for first-team games.
Gibbs has 10 England caps but has fallen out of the national-team frame while his chances have been limited under Arsene Wenger.

Gibbs is a product of Arsenal's academy, who made his debut during the 2007-08 after spending a short time on loan at Norwich City.
West Brom have so far made only two signings this summer; Jay Rodriguez from Southampton and Zhang Yuning from Vitesse but the 20-year-old has been loaned to Werder Bremen.
