I note in this EFL Cup that Premiership clubs, after putting out a team they consider capable of beating lower league sides, immediately call on first teamers to get them out of trouble when it all goes wrong. This, in my opinion, should not be allowed. If they "insult" the lower side by putting out an inferior squad then they should only be allowed similar substitutes, after all, they've got enough players to call on. I know they are obliged to play a certain amount of first-teamers, but if you only call on that few - TOUGH, treat the opposition with respect or suffer the consequences.
