Team cannot set quick players free...help!

I'm playing as Arsenal about 4 seasons in. I have very quick wing forwards (Schurrle, Walcott, a regen), and I want to develop a tactic that revolves around Ozil pinging through balls into the channels for the inside forwards to race onto and get 1v1 shots off against the opposition keeper.
Here's my two primary wing forwards that I want to be my main goal scoring threat:


However, I keep finding myself unable to get this tactic working. From watching the games, it appears that the ball is getting worked around slowly to the top of the 18 yard box, where Ozil runs out of options and passes it into a defender. Alternatively, we get a good breaking situation, and Ozil makes a horrible pass like this (in red) instead of the preferred pass (in blue):

It is trivial for the opposing fullback to step slightly forward and intercept every pass Ozil makes because he's passing to the feet or the head of my inside forwards instead of into all the space in the world and letting my winger's pace do the work.

Team tactic is (4-2-3-1)
GK
WB(S) CD CD WB(S)

CM(D) DLP(S)
IF-A AP-A IF-A/W-A
CF-A
Attacking/Fluid with the following team instructions:

Not many player instructions, but the AMC has Move into Channels, the IFs have Shoot More Often, Cross Near Post, and the CF(A) has Pass It Shorter, Move into Channels.

I've tried using the team instructions More Direct Passing and Pass Into Space, but it doesn't seem to improve my chances of getting the inside forwards 1 on 1 and greatly increases the number of passes that go straight from my midfield to the opposing centerbacks. Work Ball Into Box helps sometimes, but then I get lots of blocked shots as my team passes around the outside of the box and is then dispossessed or passes to the centerback (just like real life Arsenal).

So, FMBase community, can you help me get my players to play as I want them to? Any help or ideas would be much appreciated!
