Arsenal face competition for Montpellier defender Mapou Yanga-Mbiwa.

RMC Sports says Napoli are making advanced moves to sign him and have opened talks with Montpellier.

Arsenal boss Arsene Wenger will have to act quickly if he wants the 22-year-old to be playing at Emirates Stadium next season and will need to offer at least £13m if he is to beat Napoli in the chase to sign him.
