Most of those players didn't get major injuries, they all just had minor injuries and they have had time to recover during the international break. Vinicius, Bellingham and Militoa will all be ready after the international break, I don't think there will be any reason to not play them, The Celta game is a must-win game because they are already three points behind Barcelona and not winning that game could extend Barcelona's lead if they win Sevilla.
Check again the information of their injury! Not all of them got minor injury, dude.
There are 2 players who probably return in January and July 2025. 2 other players need to take a rest until November and December 2024. And there are 4 players who will come back in the next few days. According to the information, there are 4 players only who get minor injuries.
