The staging of the Belgian Romelu Lukaku in great reinforcement was decisive for Chelsea to win in the derby of the Emirates of London against Arsenal (2-0), who assumed his inferiority unable to question the victory of his opponent.
Lukaku, a fine acquisition by the European champion, made his debut in Premier. An injury left him sidelined in the game against Crystal Palace. Thomas Tuchel placed him at the start and it took him a quarter of an hour to score and unbalance the local duel.
