The risk of injury is always there, even in training. It is up to the technical team to better manage the players at their disposal, in order to avoid or minimize this type of problem.
UEFA's idea is for teams to start using more players, who are used less. In Europe there are more and more players, if they don't have opportunities, it can reduce interest and devalue the market. So, with the creation of more official proofs, it serves that these opportunities arise.
Of course, at first it seems strange, and there is still the mentality of always using the same players. But I believe that in the medium term, we are going to start to see greater rotation in the squads and that could increase the more exciting competition.
Yes, you're right about that, the truth is I don't know how the technical directors think in that sense, but if I were the technical director I would use the entire bench, for the simple reason of giving them minutes in important competitions, that way they measure up very well and it helps to see which players have the most potential to face stronger matches, if their mentality is to put all the best in each match, they are playing with fire, that is something that teams like Brazil do not do much, they keep and take care of enough to the quite key players, or at least those who are key to winning a game, the stars.
I don’t think there is any point in giving a player 10 minutes off an important match and judging a player based on that. We know that even elite players can have off days. And 10 minutes or even 20 minutes cannot be enough to judge how a player is going to perform in the future.
Now it is obviously a wise decision to wait and not give a young player the chance to start a match. This is because the coach thinks that he is not ready. Because we have seen multiple times that overenthusiasm can cause problems.
But it is also not right just to bring them in for the last 10 or 20 minutes and jobs are done based on that. I think if they are just trying to give the players some time and they don’t care about the match then it’s okay. But if they are trying to charge the performance of a player then I think they should bring him on around the 55th or 60th minute.
