This formation is good but vulnerable if the oppo have wingers or in 4-4-2 ,with 2 good ML,MR,use red arrows on them and playing with flanks. If so, better use DR-DC-DC-DL. If the oppo is strong, play 4-1DMC-2MC-AML-AMR-ST. It's called in formations section 4-5-1 V.3 DC, 1 DMC, 2 MC, 1 AML, 1 AMR, 2 ST
Played with def. mentality, zone,no offside, counter, flanks. Another little more def. 4-1-4-1.
If the oppo has wingers or ML-MR but only 1 ST, you can play with DR-DC-DL and DMC but your (only) DC must have same/better quality and be in form. Then you can use 2 ST with more attacking mentality.
Just to mention something. Defensive mentality in T11 it's different than real football.
With 4-5-1V, def. (but better quality team) I had many domination results (more possession-shots,scoring 4,5 goals).
Another tip. Keep an eye on shots. It's the real process of the match. Not the ball possession.
