There are not a few disasters that occur due to international matches but it is also inevitable because after all for a player when they are called to defend their country in a competition then indirectly it is like a big achievement for them so they will definitely go all out in doing their job as a player.
But on the other hand this is also sometimes detrimental to the club because in the end sometimes sometimes with the all out game shown it brings disaster and not a few clubs feel that way as we take for example this season Salah who had to be injured for quite a long time and missed defending Liverpool or Gavi who when defending Spain he actually got an ACL injury which required him to be absent for almost a season.
But on the other hand this also cannot be prohibited just like that for a club but it can still be minimized with good communication and it should be done so as not to expose their players in a match that makes this can also be minimized so that their players can play with the national team for their country but return safely and can continue to be professional at the club being defended.
For players to represent their respective countries during the international break, they'll have to travel to far distances, train under a new manager that's not the in charge of their respective clubs and then tey to blend with players from different clubs and that's why we see players suffer different sort of injuries during international break. As a result of the incessant injuries footballers suffer during the international break, many clubs do hesitate to release their top players to join their national teams during international breaks while others would simply release a statement that their top players are injured so they can be exempted from being called up to the national team.
No matter the kind of benefits players get when they play for their respective clubs, they'll never be get the kind of feeling they get when they're representing their countries and that's why it'll be almost impossible to stop these players from playing for their national teams
Actually, things like this also depend on the players themselves because sometimes in some cases there is a situation where the player forces it even though his body condition is not fine but because he really wants to show that they are one of the players who have great loyalty to their country so they force themselves harder which actually leads to problems at the club.
We can take an example when Messi was at PSG but he actually went and forced himself to defend the Argentine national team even though at that time his condition was still not fully fit which made a lot of fans and even PSG itself a little upset about it or some time ago where Salah wanted to force himself to continue to defend the Egyptian national team even though his condition was in trouble which made things like this even bigger.
Even though they also have to realize that even though the national team is a dream and surely they also certainly want to give their best for their country but on the other hand they must be able to be professional especially since they are also bound by contracts for work at the club which requires them to be able to balance the needs of the national team with the club.
