So you want us to go into matches with 2 left backs and 2 right backs on the bench? One that’s ready as a back up and one to get a few mins to bed them in? So taking up 4 sub places?
Without an unfortunately timed injury to Myko, Aznou would have had those few mins off the bench. You can’t legislate for both getting injured for the first game unless you sign 3 players for each position which isn’t tenable.
But at the same time, Aznou was signed as the backup for £8m, suggesting he is deemed ready to be back up by professionals within the sport, Apart from a load of baseless rumour on here/twotter suggesting Moyes didn’t select him because he wasn’t ready (rather than the truth of him being injured), you’ve only seen him play an hour vs Roma to make the assumption he isn’t ready.
