Yes,the quantity is very shocking Alessandro, but I still thing the training camp is an excuse. If they know that they would definitely change the training camp or use some other until the end of the season.
But I think that the medical team is the one to be blamed,remember what mistake we made by signing of Andrade ,the guy that was about to end his career ,we payed 10 mil for him he passed our medical but he wasn't able for it. That's strange.
Apart from Zebina and Salihamidzic with their 90mins per season rate of playing other players are definitely hit with injuries.
