so first off, "retain possession" shouldnt be used as a basic strategy. It sacrifices nearly any penetration/attacking intent for the sake of possession, its like telling your team to play keep-away.
Also, the shorter passing shout is usually used with a lower lower tempo, in my understanding the "higher tempo" shout and the "short passing" should contradict one another, I could be wrong however.
The play wider instruction is also contrary to a short passing possession based team.
Arsenal, for instance, who generally play a possession based slow build up system have all these CAM and CM players out wide, so there is very little width, as santi cazorla and jack wilshere are always going to cut inside with the ball.
Lastly, it seems to me that you dont have enough players making runs at the goal. As it stands, its pretty much ONLY your Striker who will be anywhere near the goal. The wingers will stay wide and deep, same with the fullbacks, and the Treq may shoot a lot, but it will all be from long range.
I see those as the most obvious issues.
