Chelsea are a strong team. The big defeat against Brighton cannot be a factor in itself. Ultimately, Arsenal lost to Manchester United in the league and no one expected it. Maybe something similar can happen in the match against Chelsea. Chelsea is a team that can beat them. Even though Arsenal seem to be the favourites, I think both teams can win.
Despite Chelsea lose to Brighton that doesn't mean Chelsea is a weak, though it was surprising how Brighton managed to win . Brighton are lucky to defeat Chelsea in the game.chelse is still tougher than Brighton despite the lose.
