Riccardo Calafiori's second goal of the season gives Arsenal a precious three points against Wolves. Both sides were reduced to 10 men as Myles Lewis-Skelly was harshly dismissed in the first half before Joao Gomes received his second yellow card for the hosts. Mikel Arteta's side remain six points behind Liverpool at the top of the Premier League. #WWFC | #AFC | #WOLARS
