Help with my Arsenal Tactic?

I didn't have the best of times with FM last year, but this year I wanted things to be a little different. I don't want a plug and play tactic and for my main saves I want to play legit. I am currently playing as Arsenal. Here is my first team squad:



I am playing a 4231 and I want to add a 433 (41221) as a second tactic once I have my players more comfortable with this one.

The roles and player instructions have changed slightly during pre-season. I can't seem to be able to fit either Ramsey or Wilshere in with Khedira (maybe not the best of signings). But due to 4231 there always seems to be a gap between the midfield and defence. I tried CM D and a B2B but wasn't working. I also loved Sanchez as a Raumeuter in the beta, but doesn't as effective anymore. I still have about £22m to spend.

Here is the line-up and team instructions:





And then here is the player instructions. Note the CB's have none. The swap positions up top was only just added, wanted to see what would happen since I was struggling to break teams down.

I mean the results haven't been awful, but they haven't been great either:



The 4-3 at Barnet was a serious low point. They had 4 shots, 3 went in.. Should not have been so close. Twente just dealt with anything I threw at them really. Although I am setting players to shoot less I am getting lots of stupid shots as well as lots of really stupid passing going on. Things like playing the ball square when there are no players, they are chipping it to each other and then having a bad touch and causing mistakes. I can't see any settings which I have set to do that?

Anyway here are the match stats from the opening games, I can provide more if need be:

Any help for a tactically inept person? I'm providing as much as I can.

I'm not expert but just keeping tactics simple seem to work as good as anything else, i'd personally have the two central midfielders much more defensive minded as you've got pretty much 4 attackers ahead of them plus the two full backs will be going forward a lot and you'll be left open especially against the bigger teams.
