Arsene Wenger: "We have talked about that because in the last two games we played against Chelsea with 10 men. So of course for the result on Saturday it will be important how we play football, but also the way we behave. We need to eliminate [Costa's] qualities and his game. You need to be committed but by respecting the rules of the game."
Antonio Conte: "I'm sure that Arsenal will fight until the end to win the title because they're a very good team, with young players, great technique, good players with good physical potential and organisation. When there are these types of games, they're very tough. It's not necessary to push any player. These big games give great emotion and great expectation. For this reason the players are already motivated."
