Preston v Arsenal: Preview and Predicted XI
At the Back
With it being a cup competition, we can expect Petr Cech to be rested meaning a start for David Ospina.
Ahead of him, Hector Bellerin, who had a poor showing against Bournemouth, will have a chance to get back on track in the cup.
In the middle of the back four, expect chances for both Gabriel Paulista and youngster Rob Holding, whilst with Kieran Gibbs still sidelined, Nacho Monreal will stay on at left-back.
