There will come a time when we will judge Mikel Arteta on his own merits. For now though, there are plenty of mental scars that linger from the Unai Emery era. Arsenal’s first defeat of the season came away to the Blades. Hence, similar to last week, Sheffield United’s visit to the Emirates serves as a benchmark for Arteta to differentiate himself. Additionally, while fourth may be a bit of a stretch this season, the Gunners have to get a move on if they want to finish in the top six.
