Dont want to be smart, or mean to you, but if you cant manage your anger, how can you manage your team ? defeat / fail / injuries are all part of the manager game.
Someone told me once, he had 15 consecutive seasons with just one or two injuries every season year, then all hell broke loose with almost 50% of his roster injured while he was out of tokens and red packs. Do I need to say he was leading the title race but ran out of fuel in the middle of it???
It has happened to everyone, so the best advice I can give is to deal calmly with it, because you cant always win.
On the other hand, if you read this and never have experienced one big wave of injuries, dont crack a smile because sooner or later your turn will come up
