Here is the problem with this tactic:-
You will get decent results against small sides, the odd 1 nil or 2 or 3 nil if they fold but if you come up against the top 6 prepare to be raped away or draw nil nil at the very best at home because the tactic is just too garbage to even perform against these sides and concedes so easily.
Your team morale will then plummet, rightfully so, especially if you are meant to be challenging for the title/top four with a team like Liverpool or Tottenham which only brings about more bad results against the smaller teams and so on and so forth.
Avoid this tactic like a drunk fat girl pinching your **** on the dance floor. It is WOEFUL!
