Newcastle boss Eddie Howe is adamant Kai Havertz should've been sent off during their win over Arsenal.
After 37 minutes Havertz went very hard into a tackle on Sean Longstaff.
The Newcastle camp were furious and it all ended with them receiving three yellow cards, while Havertz was also booked.
After the dramatic 1-0 win, Howe said: "I have not seen any replays of it. It was close to us and I thought it was high and dangerous.
"That's what I thought. I'll probably have to watch it again to confirm my opinion.
"I couldn't believe it. It's a nasty tackle from their player and then we end up with three yellow cards while they have one.
"It doesn't seem right."
