Playing through balls 'over the top' sounds a bit like an oxymoron.
If you want to go Over the Top, then Pump the Ball In the Box, Clear Ball to Flanks, Go Route One are instructions for the team.
To play balls through the defence then, More Direct Passing, Pass Into Space, Higher Tempo - this needs your strikers Running Into Channels, and players in the AM strata set to 'Attack' - wingers especially (Get further Forward PIs can help). They will then start higher up the pitch and run off the shoulder of their marker who should be part of their def line (FB/DC).
Playing through balls only works if your attackers are all up against the opponent's defensive line, have anticipation and agility to be able to turn the opposition and have the pace and acceleration to beat them to the ball.
Works well against opponents who defend high or push their full backs forward. Doesnt't work against deep lines, CDs on 'Cover' duty or have very high Pace/Accel stats.
Against deeper defenses, put your best header as Striker, play wider, then Exploit Flanks or Clear Ball to Flanks, FLoat Corsses, Pump The Ball Into the Box and Go Route One with Dribble Less and Higher Tempo. Attack or Overload.
Against Higher defensive lines, Pacey forwards/wingers - PIs Get Further Forward, Run Into Channels. TIs Pass Into Space, More Direct, Higher Tempo.
