Arsenal cruised to a 2-0 win over Wolves at the Molineux returning to the summit of the Premier League standings.
However, it was not all smooth sailing for the Gunners as one position remains a concern.
Mikel Arteta played Jakub Kiwior at left-back but once again, he failed to match the tempo needed to gel with the rest of the team.
Oleksandr Zinchenko has also struggled to establish himself in that role, meaning Arsenal have a new problem area to worry about.
Against Wolves, Kiwior barely had a few touches on the ball and was not involved in any of the crucial gameplay. He neither contributed going forward nor defended well.
More often than not, he looked clumsy on the ball and gave it away in tight areas. Also, his mistake nearly led to a goal for Wolves in the first half.
