Chelsea have announced their starting XI for their Premier League clash with Crystal Palace, and fans aren't happy to see Mason Mount in it.The 23-year-old has seen a massive drop in form this season, so much so that he didn't start either of England's UEFA Nations League games last month either. In six league appearances this season, Mount is yet to score or assist for Chelsea, but somehow continues to enjoy the trust of his club managers.Chelsea FC@ChelseaFCYour Chelsea side today! @ParimatchGlobal | #CryChe208233952Your Chelsea side today! 😎@ParimatchGlobal | #CryChe https://t.co/KQAacrnpgrHe started in Potter's first game as Blues bossagainst Red Bull Salzburg in the UEFA Champions League. Mount is now set to start in Potter's first league game as Chelsea manager.However, the Blues faithful aren't impressed to see him start the clash at Selhurst Park. They feel Christian Pulisic and Hakim Ziyech deserved to be in the XI ahead of him.Here are some of the best Twitter reactions to Mount's inclusion in the starting lineup:AB@tg10145@ChelseaFC @ParimatchGlobal Sell mount he’s not Chelsea level@ChelseaFC @ParimatchGlobal Sell mount he’s not Chelsea levelFlashWizardJr@flashwizardjr@ChelseaFC @ParimatchGlobal Mount starting??

With ten points in six league games, they are languishing in seventh position of the standings, with their European form looking hardly encouraging.The Blues have collected only one point from two UEFA Champions League games and are sitting at the bottom of their group. The prospect of a humiliating group stage exit is very much likely for the two-time winners.Chelsea FC@ChelseaFCA busy October ahead! 337963039A busy October ahead! 😎 https://t.co/4zFBed5DMXIf that wasn't enough, the Pensioners are now set to go through the knife this month with nine games lined up over the next 31 days. That includes Brentford and Manchester United in the league, as well as two legs against Serie A champions AC Milan in Europe.More sluggish performances will only diminish their chances further as Potter faces a crucial period ahead, starting with today's tricky fixture away at Crystal Palace.
