I think football injury can be discussed on this thread
⚽ Football Transfers Speculation, Odds and Predictions because it will affect the odds and predictions. I don't think there's a gambler who will bet randomly without checking the main line up, where the match will be held, etc etc. Also even though the players aren't injured, there's a chance if the managers wouldn't let him to play due to few reason or his strategy. That's why I prefer to check the main line up before the match happen than looking for injured players.
I think the OP has done the right thing by creating a thread like this, in this world cup soccer betting it's very important because I wouldn't choose to bet on a team that has a lot of injured core players. From the news circulating, Germany will not be supported by some of their players who are injured and the possibility of recovering in the near future is very small, so I will not bet on Germany. I will be eyeing Brazil and England national teams, they are at full strength to play in the world cup.
