I like Beckenbauer/Didi combo. It's just not the back 3 which I find a bit unconvincing.
..............Didi....Beckenbauer..........
Facchetti...Maldini...Figueroa...Amoros
is more than sufficient with Kaizer dropping back and moving ahead as he feels fit. Adding Moore looks to be an overkill since you have already chosen the 1970 version of Beckenbauer. With '66 version, I can understand inclusion of Moore, but not really necessary with the 1970 version.
And if your opponent's are central oriented why do you need sidebacks? Surely 2 DM smack in front of defence works better than having wide defenders?
I think I can buy this against Annah's team to counter this front 5, but agaisnt another central oriented team, it'd not be optimal at all.
5-3-2 with Pele, Stoichkov and Muller in the attack makes that front three more imposing IMO. Also it is really perfect for Stoichkov to fill the exact 94' role where he hovered all around the attack and looked for spaces. While the LWF was more natural to his game, in this formation he is close to that 94' form as you get and makes him even a greater danger with Facchetti overlapping on the side.
I can understand a 4-2-3-1 approach and of course I thought of that but IMO with Moore as last line of defence makes the it even harder for some of the great attackers to find space and score. I'll make some gifs probably on the mechanics defensively, but basically it's what I've explained above.
Generally the idea is to have 3 at the back not to be susceptible to counters with Moore pushing up in possession in the hole, when Beckenbauer moves forward. There won't be any free space in the center for the opposition forwards and while Figueroa most of the cases takes care for Nordahl, WM of what Annah opted gets the ball wide while putting attackers in the box. I'd rather have additional defender in the box rather than a midfielder.
Having only Beckenbauer doing the running through the lines would mean an awful lot of work to do which would negate the effect he can have on the midfield.
The only negative I can see in playing against Barca 4-3-3 type of press but then again even the defenders in Moore, Maldini and Figueroa are technically excellent that to bother them.
There are always variants of course but against another central oriented attacking team it's exactly the same I see it - saturating the center with defensively great players who have specific zones and responsibilities operating in specific ways. For example against another 5-3-2 the full backs will pick the full backs, one of the CB's will mark the opposition forward, while the other offers protection if the ball is wide, Beckenbauer will look for the #10, while Moore is the last line of defence and would cover if someone gets beaten not to open up space and create numerical advantage in attack.
Both full backs are excellent in attack, Facchetti for example scored nearly 100 goals in his career and his distribution is also admirable. With both of them running into space and 3 highly mobile forwards in Stoichkov, Pele and Muller, support of Beckenbauer and Didi I don't believe this side lacks anything in attack, quite the opposite.
