Ulloa starts for Seagulls
Leo Ulloa has been handed his Albion debut – from kick-off.
The recently-signed Argentinian starts in attack in the the FA Cup fourth round tie versus Arsenal at The Amex.
He will be flanked in attack by Ashley Barnes and Will Buckley.
Casper Ankergren, who kept a clean sheet against Newcastle in the last round, again plays in goal.
The Seagulls face a massive challenge if they are to repeat that feat against the Gunners.
Alex Oxlade-Chamberlain, Lukas Podolski and Olivier Giroud team up in a powerful looking front line for the visitors.
Jack Wilshere, Theo Walcott and Santi Cazorla are among their subs.
Albion: Ankergren, Calderon, Greer, El-Abd, Bridge; Bridcutt, Hammond, David; Buckley, Barnes, Ulloa. Subs: Kuszczak, Painter, Dicker, Orlandi, LuaLua, Vicente, Mackail-Smith.
Arsenal: Szczesny, Jenkinson, Mertesacker, Koscielny, Santos; Diaby, Ramsey, Rosicky; Oxlade-Chamberlain, Giroud, Podolski. Subs: Mannone, Sagna, Gibbs, Wilshere, Cazorla, Arshavin, Walcott.
