Arsenal are being linked with Young Boys fullback Francois Affolter.
The Daily Mail says the Switzerland international has been attracting interest from Premier League clubs.
Several are looking for full-backs who can also play centre-back and the 21-year-oldm available for £1.5m, has the ability.
Arsenal, Reading, Norwich, Swansea and Newcastle are all understood to have been approached. The Gunners, who are ready to loan out Ignasi Miquel to Brighton, want a fourth-choice centre-back who can give defensive cover.
