Defensive tactical help

ive just recently start playing Fm 2010 and have chosen a lower class team, Ajax CT. im having a problem with my team, cause my defenders keep coming up and leave a massive gap and my centeral midfielders dont defend at all. how do i get my midfielders to do more tackling and get my defenders to defend in the box more?

well defense wise you an get them to play deeper (team instructions advanced) this makes them play more defensive and leave a biger gap inbetween the defenders and the midfielders, although this makes it harder to put pressure on the opposition.

midfield wise, I would suggest playing them more defensivel, and if they are good at tackln set it to hard tackles... , along with the correct player instructions this can do wonders if used correctly..

Hey i used to have this problem a lot, i play as newcastle as ive supported them my whole life and even though they have the best team in the championship i was still leaking goals like crazy!

Rather than it being any team instructions i had set it was my player instructions, defenders were committing themselves too early and allowing the strikers to skip past them.
One thing u can try is to set your instructions on Closing down to Stand off more, that way they will just slow them down and allow the midfield to join in the defence.
What works for me though as i have Steven Taylor And Coloccini i set taylor to be a stopper as he has the right stats and coloccini to cover meaning that if the pressure taylor puts on the attackers doesnt pay off then coloccini can just sweep up as he has good anticipation and positioning. Hope this may help
