Taking advantage of a Tanking Team

If a Manager is tanking and has all their players down either side of the pitch which are out of position is it best to play straight through the middle with tactics?
Do normal tactics just go out the window and should i just play any narrow formation straight down the middle to take advantage?
Just on paper his team is very good
surely i still have to take care of all the overlapping wide men or should i focus on down the middle regardless?

You don't have to do nothing tactically,just play a normal formation.

yes, play normal.
Every time I tried to take advantage from one side (when oppo manager wasn't present and his DL or DR took a red card), it was a fail :(

Just play your normal formation.
