Tierney's role reversal
It's perhaps weird to think that if Kieran Tierney had missed three games last season, Arsenal would most likely have found themselves in a position where they would have lost all three. The Scottish international missed much of preseason due to injury and conspired to be absent from the starting XI for all three of the Gunners' opening three games, but with the arrival of Oleksandr Zinchenko Arsenal found themselves in a position to cope unlike in years gone by.
However, when the news filtered through just before kick off the the Ukraine international was going to be absent as a precautionary measure due to a sprained knee, questions began to be asked. They were not necessarily over the quality of Zinchenko's replacement. Tierney after all, has been one of the most important players in the Arsenal squad for years now and his absence at the business end of last season is arguably what cost them Champions League qualification,
