I am having exactly the same issues as yourself.
FA cup fourth round Vs Burnley, I have no game after this for 6 days so can play quite a strong squad.
Lewandowski, lennon, de jong, bale, sandro, parker, alex sandro, kaboul, vertonghen, walker, friedel
Scouted their team, very weak fullbacks (compared to my players), physically weaker and slower, their moral is on the floor while my players are all green and some with superb moral.
We are going into this game 4 days after north London derby win against Arsenal (2-0)h
We got beat up, Burnley (it seems) played us off the park.
BUT...my fullbacks just walked EVERYWHERE and did nothing when being closed down, they had support players to pass to and didn't. My two rocks in centre midfield where useless caught in possession time and time again (OFF LOAD THE FKIN BALL FFS!).
We seemed to love getting to the eighteen yard box and then passing it back bit by glorious bit until my keeper has the ball again!!.
Lewandowski had superb chance, open goal with clear sight 8-10 yards out....and he turns 180 degree's lays it off to walker some 5-10 yards OUTSIDE the eighteen yard box who then shoots and misses by a fkin mile.
I love Football, I hate Football manager 2013 WITH A F****** PASSION
(Burnley won 1-0) :S
