It's not just the training, it's just over using players as well. Which ultimately comes when you don't trust rest of the squad.
Arteta now admitting saliba was injured in warm up. Then still plays him

which is just sheer gross neglect and incompetence.
On a side note fair play to Mosquera who came in and did a job. With also the left side CB signing, we should be able to rotate more as a squad.
Until the midfield creativity issue is addressed we will keep seeing these toothless midfield displays from our team. Reality is that had havertz been fit today, Arteta would have have just shoved him in there instead of merino which would have be an equally as bad
Eze should have started in ten, unfortunately Arteta ain't brave enough to try Nwaneri or dowman in their from the start.
We are going to get more injuries this season, do we have a squad to cope? Yes. But sadly we don't have a manager capable of managing a squad under adversity.
I'm already dreading the borefeast we will see when we play Newcastle away. Playing not to lose, doesn't win a team league title. Gyokeres can't make the difference if he's getting zero chances due to no creativity.
