Crystal Palace boss Alan Pardew is unhappy with their treatment by match officials.
Pardew believes Palace's lightning wingers deserve greater protection from referees, with opposition defenders getting away with careless challenges even after they've been booked.
He said: "In the period I've been at Palace, we've not had an opposing player sent off. We've got flying wingers and it never happens to us.
"There has been a couple of times that the call has not been good for us. We've had some incidents with three or four challenges after a yellow card. It's a bit frustrating.
"My view of the general standard of the Premier League is high, but that doesn't mean to say it can't be improved."
