Brentford have identified Nuremburg’s Robin Hack as their first-choice replacement for Said Benrahma should they lose their star winger.
West Ham and Aston Villa are strongly interested in Benrahma and other Premier League clubs have been linked with him.
Brentford will target Hack, 21, if Benrahma leaves Griffin Park this summer.
The Germany Under-21 international made 31 appearances in the Bundesliga 2 last season, scoring 10 goals.
Brentford are also on the lookout for a central midfielder and right-sided centre-back.
A number of left-backs have also been identified as potential replacements for Rico Henry in the event of him being snapped up by a top-flight club.
