West Brom will get better - Hodgson

West Bromwich Albion manager Roy Hodgson promises his side will improve after losing 3-0 to a "rampant" Arsenal side at the Emirates.

Hodgson admits the Gunners' third goal "killed" the game for them but praises his players for "sticking to their guns".

Robin van Persie scored one goal and made two more as Arsenal secured a fourth consecutive Premier League win.
