The biggest problem for Arsenal last season was the defence, though the midfield hardly covered itself in glory and on the face of it, Unai Emery is doing the right thing at long last.
It does seem that at a very minimum three defenders will be gone and it can be argued that more need to be jettisoned as well but sometimes it can be counterproductive to make too many drastic changes in one go.
Stephan Lichtsteiner is already gone and it is almost certain that both Laurent Koscielny and Nacho Monreal will follow him out of the door.
That is three defenders from a squad of ten and it can be argued that Shkodran Mustafi and Carl Jenkinson should also be on the exit list but offloading 30% of your defence is still significant.
It is hard to conceive a squad with less than ten defenders, especially when you consider we will be battling it out on four fronts next season and so you have to believe that at least three new defenders will be in the squad next season.
For some that will not be enough but for me, it is far better than the status quo and if the three newcomers are good enough it could make a world of difference at the back.
Of course, we are limited with our budget but there have been a lot of rumours linking us with enough defenders at reasonable prices that I believe getting the right sort of player is achievable.
But as things stand right now, I am satisfied with what I am hearing, it seems to me that Emery knows what needs sorting and is getting on with it.
