Matip was hardly ever injured in Germany.
He wasnt and don't get me wrong, I would question why players like Alisson gets injured a lot for a goal keeper.
But generally the biggest predictor of future injuries is past injuries and if we are listing our most injury prone players then most fans would have Konate, Gomez, Thiago, Jota at the top of that list and low and behold, 3 of those had history of having injury issues before they joined us.
I really like Olise, but if we were to sign him and he spends a number of weeks out next season with hamstring injuries, then we only have ourselves to blame.
