West Brom are facing competition from PSV Eindhoven, Bordeaux and Sporting Lisbon for the signature of free agent Kevin Constant.
Reports in Portugal claim the former AC Milan defender is attracting the interest of several top-flight clubs across Europe as he considers his next move.
Albion’s interest makes sense as head coach Tony Pulis looks to add further competition at left-back, although the Baggies did sign Brendan Galloway on loan from Everton for the rest of the season.
Constant, a Guinea international, is vastly experienced after spells at AC Milan, Trabzonspor and Bologna.
The 29-year-old signed a four-year contract on wages of £36,000 a week at Trabzonspor in 2014 but, last November, the Turkish club terminated the deal after less than two years and paid him off.
He then joined Bologna on a six-month deal with an option for two more years but the Serie A club didn’t take up the option after he played in seven league matches.
