LONDON: David Luiz was sent off for a rash challenge on Sead Kolasinac as Chelsea and Arsenal played out a scrappy 0-0 draw at Stamford Bridge in the Premier League on Sunday.
The Brazilian was given his marching orders three minutes from time in the most notable incident from a drab encounter between two supposed title challengers.
Chelsea's chances were more numerous, but Arsenal defended well throughout in a very disciplined display from the visitors.
The Gunners had the ball in the net 14 minutes from time, but Shkodran Mustafi was correctly adjudged to have been offside when he headed home.
Chelsea looked the sharpest early on, but Arsenal carved out the first great chance, Danny Welbeck heading wide after an excellent ball from Hector Bellerin on the right after 16 minutes.
Moments later, the Spanish full-back set up another chance for Alexandre Lacazette, but the Frenchman's shot was easily held by Thibaut Courtois.
Pedro then squandered an opportunity to put the hosts ahead at the midway point of the first half, but his effort on goal was too tame after he was put past the Arsenal defence by Cesc Fabregas.
