It's not about the 433. It's all about the squad we had, the squad we had was amazing in those three seasons. We could play 451, 442, 433.
1) Our midfield in those season love to close down players so quick.
2) And our defense were so solid and consistent.
3) And we played with really high tempo and pace.
4) What even better was we got a lot of versatility players who can do the job nicely done.
Tevez was a hard working man, and he could play as a striker or wide.
Rooney could play the same role as Tevez.
Ronaldo well what can I say. The best in those seasons.
VDS, Giggs, Scholes and Neville for experience.
And our defenders were probably the main MVP.
Brown, Carrick and Hargreaves did their job nicely, Hargreaves could play as a right back and cover Brown position, and when Vidic was injured.. Brown did his job really well to cover Vidic.
The big match player especially against Barcelona and Roma. Park Ji Sung
Anderson used to be so energetic, probably turned into shit because we pushed him too much in a deeper role.
Our players are just too lazy right now, they don't closed down players quickly, lack of pace and energy, can't play in a quick tempo and the defense are just inconsistent.
