Is that how you measure whether things were worse or not? Has an example Varane registers at least 3 injuries and Shaw 2 but both of them missed less games than Valencia and Shaw who missed more games in 15-16 but only register 2 combined injuries? Also for roughly 4 months we had anywhere between 10 and 14 first team players out while having a very shallow team unlike our current one.In the season with the worst injuries under LVG, the squad had 39 injuries.
This season under ETH, the squad had 60 injuries.
Even if you were to conclude that this year was worse, it's by a fine margin because the 15-16 team largely had long term injuries to important players and we had a shallow team that had to rely on the likes of McNair, a young Lingard and eventually Rashford.
