I really think that make this competition every 2 years would be too much: the majority of players from the big club would play non-stop because every single year there would be an international competition: Euro cup - Club World Cup - World Cup - Club World Cup, without forgetting the Copa America and the African Cup. The situation is really getting out of hand.
That’s what I saw from this competition, one moment they had a season just ended and the next, they were into another competition which I found very stressful for the players. Sure
you might not see them complaining, they have to play, they have to entertain the fans and be loyal to the club but, they are really being worn out and really don’t get the chance to a personal life and family that much. Perhaps they could have a better fix to these competitions so we don’t loose our players to injuries and strains.
Actually several players already complained in the past months/years about the too many matches they have to play, and this of course has an impact on their performances because they are more tired and more prone to injuries. I don't want to defend players that earn in one earn what we'll never earn in our full lifetime but they are humans as well, they can't play every single year with barely 2 weeks off, it's not even good for the entertainment at a certain point.
