I make that 8 first teamers, 10 if we include the two more potentially out because of Covid. Injury lists are readily available and up to date across the web for Premier League teams (used for things such as fantasy football). Having a quick look, there is not one Premier League team with the amount of first teamers out injured that we have. Arsenal have 8 out (which includes 3 due to Covid) and they’ve roundly been labelled as currently having an injury crisis. So yes, going by this I believe we get a ridiculously high amount of injuries that is largely incomparable to most other clubs (at least in the Premier League).
