@icedgate You're totally wrong. Now I manage a team in Ukranian Second Division. I only have two good defenders, two good midfielders and a striker who can score some goals.
Now that I know what I have at my disposal, I decided to go with a bog standard 442 and it really works well. Let me show you the tactic first:
SKS
FBS CDD CDD FBA
WMA RPM BBM WMS
AFA DLFS
My team is above average at best so I adopted a normal approach.
Mentality: Balanced
In-possession instructions: None
In-transition instructions: Distribute to CBs and Take Short Kicks
Out-of-possession instructions: Higher DL, More Urgent, Tighter Marking, Use Offside Trap, Get Stuck In
PIs:
FBA-Stay Wider
WMS- Sit Narrower, Run Wide
WMA- Stay Wider, Run Wide
My game plan is to play out of defence as much as possible although they can prefer direct balls to the strikers or the right midfielder at times. When the opposition has the ball, I try to win the ball in the middle of the park like Yorkshire terrriers. Then, the team either use the left flank for a cross to the far post, or a through ball for the strikers to run onto or a cross/cutback from the right midfielder or even an odd ball over the top by the right fullback.
As @Cleon said, every tactic needs support, movement, penetration, width, mobility, and creativity and my plan provides all of them.
Support- All players have close passing options when they are on the ball. RPM is pretty crucial here.
Movement- The WMA keep the channels open for AFA by running wide
The WMS opens up some space for FBA
DLF drops deep to support the midfield and creates decisions crises between defenders
AFA provides the much needed height for the creative players behind him.
FBS is always an outlet for WMA or unmarked at times for a deep cross or a cutback.
Penetration- AFA attacks the space behind the space, FBA and WMA attacks the wings while our BBM, DLF and RPM are runners from the deep and you can't mark the players that move.
Width- It comes from the FBA and WMA. They stretch the opposition horizontally by staying wider.
Creativity- FBA-WMS- RPM or BBM -->third-man run combination
DLF/WMS-RPM-AFA--> third man run combination
FBA/WMA- a cross/cutback
WMS-RPM- through balls, diagonal balls
WMA-AFA 1vs1 duel
Mobility- The midfielders roam the area in front of the opposition defence at will to provide the crucial support to the players around them.
Pretty simple, right?
