Arsenal boss Arsene Wenger faces a battle to keep hold of defender William Gallas.

The Daily Mail says Wenger will be delving into the transfer market for central defenders this summer, when Gallas, Sol Campbell, Mikael Silvestre and Philippe Senderos are out of contract.

The manager wants 32-year-old Gallas to sign a new deal - bending his rule of only one-year extensions for players over 30 - but there is competition from Paris Saint -Germain and Roma.
