These two sides drew 1-1 earlier in the season, at a time when Chelsea were surging and Palace were struggling, so this could be a tough game for the Blues. Palace have lost only one of their last five games in the league, which was against Arsenal, while Chelsea are winless in their last three.
Both teams to score has occurred in four of Palace's last five and three of Chelsea's last five, so that looks like a pretty likely outcome in this one. Ultimately, we think the shares will be spoiled in what is a tough game to call. Crystal Palace 1-1 Chelsea.
