think they key word here is "high" but that actually means whole pitch, it doesn't just mean that you pressing in attack but you'r pressing the opponent everywhere in the pitch i guess.
as i said i use high pressing cause i want all 5 mids to give their best and not just 3 of them. that's how it works for me on topeleven

It's something like playing like Barcelona this season, they aplay pressing almost everywhere yet their MCs play defensive most of the time and cover big areas, allowing DL/DR to go forward in the middle of the pitch..
