Speaking about midfield trio in 433, I think my all time favorite would be Lampard, Essien and Makelele during Mourinho era.
Makelele was incredible in his position,and this is why the defensive midfield role are often called as the Makelele role nowadays.
The 433 under Mourinho is most effective against 442 formation. I remember Mourinho once said that, under a 433 formation, the team will always have advantage against a 442 team where the team only has 2 midfielders side by side.

‘Look, if I have a triangle in midfield – Claude Makelele behind and two others just in front – I will always have an advantage against a pure 4-4-2 where the central midfielders are side by side. That’s because I will always have an extra man. It starts with Makelele, who is between the lines. If nobody comes to him he can see the whole pitch and has time. If he gets closed down it means one of the two other central midfielders is open. If they are closed down and the other team’s wingers come inside to help, it means there is space now for us on the flank, either for our own wingers or for our full-backs. There is nothing a pure 4-4-2 can do to stop things’.
I like Malouda-Lampard-Ballack trio under Carlo era too. Those rampaging wins!
