Arsenal have cruised into the FA Cup fifth round after they beat Coventry City 4-0 at the Emirates Stadium. The returning Lukas Podolski scored twice before Santi Cazorla and Olivier Giroud were sprung from the bench to finish out the scoring against the League One side.
The Gunners cantered into an easy 2-0 lead with great thanks to the predatory Podolski. They completely outplayed Steven Pressley's team in a very one-sided first half.
The visitors gave a much better account of themselves in the second period and should have reduced the deficit when Leon Clarke hit the base of the post with Lukasz Fabianski beaten.
Just as Coventry were beginning to put the match on an even keel, Arsene Wenger took the very disappointing Nicklas Bendtner off for Cazorla. The little Spaniard was the very last player the Sky Blues would have wanted to face in the final 20 minutes.
Giroud was introduced as Podolski made way and Gedion Zelalem made his Arsenal debut at just 16 years of age.
Cazorla and Giroud both scored to put a gloss on a game that was perhaps cruel to Coventry.
