Emile Smith-Rowe and Pierre-Emerick Aubameyang scored in extra time as Mikel Arteta's side began their FA Cup defence with a hard-fought 2-0 victory over Newcastle United in the third round at Emirates Stadium on Saturday.
Substitute Smith-Rowe was initially shown a straight red in stoppage time by referee Chris Kavanagh for a tackle on Matthew Longstaff before it was downgraded to a yellow card following a VAR review.
