With Unai Emery not losing a domestic cup game since May 2016, his Arsenal side kept their boss' personal winning streak going on Wednesday night and left their manager duly impressed.
The Gunner's were led by a brace from Danny Welbeck in the first half which gave them what they thought would be a comfortable advantage, but a stubborn run from the persistent Championship side almost saw them even the score as they managed to pull one back with a successful set-piece from Alan Judge. Arsenal weren't too fazed, and a stoppage time strike from Alexandre Lacazette sealed the deal with the scoresheet showing 3-1 by the end.
