Your logical fallacy is assuming (at least implicitly) that anyone CAN, and therefore should, just become better footballers by the virtue of being selected to start matches. And this can’t be blamed on the coach alone.
Not to be ableist, but if I picked a guy in a wheelchair to start as partner to Maguire he would most likely not be up to the task. Though I firmly believe he would gift fewer goals than Lindelöf, I very much doubt he could be a mainstay in our back four. Purely selecting him would make me look retarded.
I am not claiming Ole is retarded, but there is not an ounce of end product in Lindgard, and that has been clear for most fans for 6-7 years. If Ole starts him, he IS responsible for his lack of end product simply down to the fact that this is a player severely lacking in finishing, passing, positioning and composure. He can’t just train those qualities into his game at 27. He doesn’t have them and he never will.
Starting this man is criminally bad management.
