The trouble is, that to some teams it's just accepted now that it's fair game to target certain players without regard for the rules.
This was an extract from a report on the Norwich game.
"Mark Robins was angered at the lack of protection Tatsuhiro Sakamoto received as he was clearly targeted by Norwich enforcers Marcelino Nunez and Kenny McLean, both of whom were booked for cynical tackles on the Japanese winger inside the first 45 minutes."
“You’ll have to ask him (David Wagner) whether it was a tactic to kick him out of the game, because that’s what it looked like to me,” Robins said. “He gets absolutely zero protection from the referee and then he ends up coming off, and probably bruised and battered for the next few days"
This was Wagner's response.
"CoventryLive duly asked Wagner if it was part of his game plan to target Sakamoto, to which he made no apologies, admitting: “Yes, obviously Sakamoto and O’Hare are two of the standout players in the Championship and good players for Coventry, and if you want to be successful you have to try to get them calm. I can only praise my whole team because it was a team effort to keep them calm, so big credit to my players"
