Arsenal picked up a third consecutive Premier League win on Saturday as they beat Hull City 4-1.
Alexis Sanchez's double and goals from Theo Walcott and Granit Xhaka made the difference for the Gunners, who recovered from their midweek draw with Paris Saint-Germain in the Champions League.
The Chile attacker opened the scoring after just 17 minutes and could have doubled his tally when he stepped up to take a penalty, but failed to convert.
Having Jake Livermore sent off in the first half made it a seemingly impossible task for Hull to get anything out of it, and Walcott made things more comfortable when he added a second goal in the 55th minute.
Things got a bit nervier for Arsenal towards the end with Robert Snodgrass converting a penalty, but Sanchez was on hand again before Xhaka fired one in to round off a comfortable afternoon.
