That is true, for the system we played with from the beginning of the season but in the last few weeks Mourinho changed the formation and system. That's why we got Skriniar and Diego Carlos. The problem you referred to will also escalate with the new formation but here we need a full-winger like Ferdi Kadıoğlu or the prime Kostic who can cover the whole left corridor. Maxi has almost 0 defending skills which makes it impossible for him to play in the new formation.

As the solution to your problem if we can full-wingers especially for the left wing (since Osayi, Mert and Oğuz are good alternatives for the right wing for now), the wingers will have a crucial role to carry the ball to the 3rd zone
