Arsene Wenger admitted his Arsenal squad is short of firepower despite in-form Olivier Giroud's double in the 3-2 FA Cup fourth round win at Brighton.

Giroud struck twice to see off the combative Championship outfit three days after his double in the 5-1 Premier League defeat of West Ham.

The France striker's performance drew praise from Wenger, but the Gunners' manager conceded he still lacks sufficient cover up front, particularly with Gervinho away at the African Cup of Nations with Ivory Coast.
