High ball control, agility, passing skill and vision. Unleash your undead army and dominate the field.
+ High possession %
+ Scoring a lot once team is confident with the tactic
+ Solid defense
+ Unstoppable tactic with the proper players
Try to get Defenders with high passing skill (Laporte, De Ligt, Van Dijk etc.) depending on your budget.
I suggest you two great IFs (example Neymar - Messi world class or young players such Sancho, Martins, even Pepè). This is your highest priority.
At least one tall Midfielder (high priority) but the three of them with 14+ passing skill and ball control.
Rest is up to your creativity. Show me your results and let me know if it's working for you.
