Arsenal are the first team into the fifth round of the FA Cup.
The Gunners shot down League One side Coventry City 4-0 at the Emirates.
The home side blasted themselves into a two goal lead at the interval with a brace from Lukas Podolski.
Coventry acquitted themselves well in the second half and Leon Clarke hit a post.
But the superior class sprung from the Arsenal bench proved too hot to handle and subs Olivier Giroud and Santi Cazorla wrapped the tie up with further goals in the last ten minutes.
