Not a viable analysis, in my view.
Firstly, considering how many shots and chances we create, it's hard to conclude that the problem is that our midfield and defence is being stifled. If that was the issue, then it'd turn up as a shortage of shots and scoring chances. Which is simply not the case. By all measures, we are not just dominating possession more than we've done in the past, we are also producing a high volume of offensive pressure and scoring chances. So opposing teams have not been able to prevent us from creating offense. Only City and Liverpool have created more (based on xG). That is not to say that the midfield has performed very well, or that we wouldn't produce more if it worked better - but that flaw clearly is not enough to stifle us offensively. The problem - at least in some of our games - have rather been what we do and don't in the attacking third.
Secondly, we were not by any stretch of imagination outplayed or out thought by Villa today. Not in terms of dominance, not in terms of tactics. They took one of their (few) chances, we did not take ours. If we had, we'd have won. Even though they probably played more or less up to capacity and we didn't.
