So, I think Arteta, as Arsenal's coach, clearly shouldn't be satisfied with Arsenal's current performance. Because basically, if Arsenal is only satisfied with their current performance, it is clearly not good. So, currently, Arsenal clearly needs to buy some new players, and Arteta must create a good attacking strategy. So, Arsenal doesn't need to be fixated on a playing style that relies solely on defense, because basically, that will clearly not work when facing strong teams. So, for that reason, Arteta clearly has to create a good attacking strategy for next season, so that Arsenal's performance can be even better.
You are not out of context with your taughts actually but you twisted the whole brief idea to become long. It is general knowledge that Arsenal has built a great strength in their defence which they are now known for. One thing I know about building strength is that it could be all at once or segmented which I suppose is Arteta style.
It is time he begins to build strength in other areas since it is now clear how much strength he already got in his defence. It may not necessarily be about buying players but an improved strategy that will get the front line and attack working really well. But if it becomes necessary he buys players he surely should.
