The FA Cup is fine on its own. We don’t need the EFL Cup too. Most clubs priorities the FA Cup way more, it’s a more prestigious prize and the tournament has way more fixtures. Clubs also prioritise league matches over the EFL Cup anyway, so the EFL just adds to the fixture congestion of a lot of teams. Players are getting injured across every team anyway.
During a busy fixture schedule, clubs have to put together a team to play in the EFL cup midweek whilst trying to save their best players for the important league match 3 days later, but also trying not to get humiliated too badly in a Cup game that most teams don’t really care too much about.
Even though I am for smaller clubs unfortunately it will probably cease to exist soon. They already stopped playing the league cup in France.
