Advantages:
- Quick training (base speed 4,5-5)
- Cheaper trainees
Disadvantages:
- 4 + 4 trainees (Wingers train at 100% and wingbacks at 50%)
- Lower tactical variability
trainer winger is one of the most flexible formation...
though u have to keep 2 Wingers and 2 WB...
u can play 4-4-2, 4-3-3 (better CA), 5-3-2 (better CA), 3-4-3, 3-5-2, 4-5-1, even 5-4-1
actually i regrey not training Winger at the start of my team...
