But do u think this formation can be used as a defensive tactic especially when faced with stronger opponent?
yes, that's why I write that it depends from oppo quality. If he is strong, no.

Passing style short
Force counter
hmm, no. short passing doesn't fit with counters (on paper of course).
better mix

Hard tackling
risky vs high q oppo. Maybe too many fouls and dangerous F-K.
Better m-t-m
