I wish Jose could transform Manchester United's attack with that efficiency

Not sure if anyone has noticed this:
Once you arrange a friendly with Mourinho FC, his team will have 7-8 players in GK position.
I am thinking that game takes cumulative quality of all those players for his GK, hence we cannot score against him.
Also, since all but 1 of those 7-8 players is a GK, he gets a possession penalty.
Hence, we see the possession stats as 70-30.
Not sure if these are bugs or intentional design to prevent his team from getting defeated
