If the law seems heavy-handed, it is to protect the attacking player. Look again at Szczesny’s challenge on Robben and you see a foot strike a planted leg, which might have cracked on impact. For that reason it was unbecoming of Wenger, the Arsenal manager, to taunt Robben with a mock diving gesture. If Wenger stands for one thing it is creativity and expressive football. For him to jump ship just because one of his players was on the receiving end of a correct refereeing decision showed that objectivity is becoming impossible in modern football.
