Gavi is not the only player who has been given this exact fee for having been Injured, same share has also being assigned to Camavinga who was also Injured during the international break. Both positions in the different clubs will miss this players both. Real Madrid also have sent his heart felt sympathies to be strong.
But this is kind of a short-sighted way of looking at things. I am not offending you, but there are so many young players that do not get injured. It is a factor and I agree with that, but players are also extremely different in responding to physical stress and sometimes it is just plain brutal attacks against a joint or other part of the body, which doesn't have much to do with fatigue. But I think all these games with the national teams are too much because there is not only all of this qualification stuff for the World Cup and the European Championship, but also the Nations League and then sometimes friendly games. I think this could be reduced, but I guess there is money involved and every organization wants a piece of the pie.
Real Madrid is going through this with Vinicius Junior as well and know what it means for a player to be out for such a long time. It's nasty for everyone.
