David Luiz was rightfully sent off, according to Arsenal boss Arsene Wenger.

The Chelsea defender given his marching orders after he brutally mistimed his tackle on Sead Kolasinac.

When asked about Luiz's challenge, Wenger replied: "It was excessive force, yes, and I think Kolasinac was not completely on his feet and eased a bit off.

"I think even Luiz, with a bit of distance, will accept that he went in too strongly.

"After that, it's the decision of the referee that you have to accept. I haven't seen it again but it looked to me like it was excessive force."
