Okay, it seems with the poorer teams, using v1 is producing better results. While a team with a better base squad revels in using v3. This tactic seems to push your team onto the next level. Being honest, Southampton have got a decent squad, with a few signings they can be a top four team.
My Wigan side has got a fair few talented players, by no means top 6 but the tactic seems to push an extra 20% in the run of a season.
Losing to Liverpool away 3-1 is by no means a bad result for QPR, I've had a few whoopings using this formation too. using it over a full season is where this tactics shows its quality.
