I got an opinion the game likes to troll people, for 4 seasons I never got a GK, but this season I trained my existing keeper until 117% while the rest of the team remained at 108% , then suddenly the game decide to recommend me 3 GKs?
It probably thinks you need another one to go with him, to cover for injury and suspension...
Any formation or tactics advice given is based purely on experience with my teams...
