They should have got him in before anyone else. He was a bargain for the quality he has. They've prioritised the wrong areas which is surprising because it has been clear for a while how poor they are defensively. Scoring goals was never the issue.
As for the GK, 100%. Arsenal moved for Raya even having bought Ramsdale not long before, because they knew even a small gain in that area was fundamental to success. They decided to ignore their problem position up front though.
We're in with a shout this season purely because whilst the club didn't act post-treble/4 in a row, we soon learnt our lesson and strengthened the areas we needed to. We needed a refresh and we got it.
Arsenal should have got attacking players in sooner. Had they, not only could they have won the league last year - they'd have been much better this year too. The door is ajar for us if we can continue to improve.
