Haven't used had him ever,but my proposition as i see him is this:
play him prefferably as an AMC with an arrow to ST.if you have good wingers and a ST with good header then don't use him as target man.if the other ST is fast,use djokic as target man,but with ball on feet.don't let him hold on ball or run with it.have him try a lot of through passes.
that's my thought.i'm not sure,could be crap.if you decide to try it please tell me how it went. |
