Unequal teams

Being a football fan I was disappointed to see the state of the Deaf School's table football.  The dust and small stones add authenticity to the pitch but there is a problem with one of the teams.
Q Can you spot it?
A The yellow team has 13 players however the red team has only 12, and two of the red team don't have any legs, which is a big disadvantage in table football.
My cunning plan is to use plenty of WD40  (you can imagine the rust because it is kept outdoors) and a screwdriver to remove the two injured red players and two of the yellow players and then transfer one of the yellow players to the red team.
I'd better get permission before I make any improvements because the disadvantaged red team has probably been like it for many years and there might be a complicated scoring system in place which allows the teams to play on equal terms - although I doubt this very much. Pete
