Olise gets the game underway for Palace!
Hello and welcome to live coverage of the Premier League meeting between Chelsea and Crystal Palace at Stamford Bridge!
Chelsea are going through a very rough patch, sitting in 10th in the table and coming into this game having won just one of their last 10 league games (D3 L5). Graham Potter will be looking to turn things around after being beaten in three consecutive matches in all competitions, with a 2-1 loss to Fulham in midweek following back-to-back defeats to Manchester City in the Premier League and FA Cup respectively. Palace sit just three points and two places below their opponents in the table and have won just one of their last five outings in all competitions (L4), but that victory did come in their last away match against Bournemouth.
CHELSEA STARTING XI (4-3-3): Kepa Arrizabalaga; Trevoh Chalobah, Thiago Silva, Benoit Badiashile, Lewis Hall; Conor Gallagher, Jorginho, Carney Chukwuemeka; Hakim Ziyech, Kai Havertz, Mason Mount.
CHELSEA SUBS: Bashir Humphreys, Cesar Azpilicueta, Pierre-Emerick Aubameyang, Datro Fofana, Kalidou Koulibaly, Mateo Kovacic, Marcus Bettinelli, Ruben Loftus-Cheek, Marc Cucurella.
CRYSTAL PALACE STARTING XI (4-2-3-1): Vicente Guaita; Nathaniel Clyne, Joachim Andersen, Marc Guehi, Tyrick Mitchell; Cheik Oumar Doucoure, Jeffrey Schlupp; Michael Olise, Eberechi Eze, Wilfried Zaha; Jordan Ayew.
CRYSTAL PALACE SUBS: Will Hughes, David Ozoh, Luka Milivojevic, Odsonne Edouard, James Tomkins, Joel Ward, Sam Johnstone, Jean-Philippe Mateta, Chris Richards.
The teams are out on the pitch now, with kick-off just moments away!
Potter looked fairly pleased with Chelsea's performance in the first half, but he'll be looking for them to be more clinical after only having one shot on target. Vieira will be happy with how his side played as well, with them putting Chelsea under real pressure at times, and he'll be hoping for more of the same.
Chelsea end a run of four games without a win, but they stay in 10th, level on points with Liverpool, who they face next Saturday. Palace have now lost their last three matches on the bounce in all competitions, and they stay 12th. They host Manchester United on Wednesday.
