Chelsea have shot themselves in the foot on multiple occasions throughout the season and were simply not good enough defensively in their 2-2 Premier League draw to 10-man Burnley, attacker Cole Palmer said. Palmer’s two goals were cancelled out by strikes from Josh Cullen and Dara O’Shea as Chelsea dropped points despite having a man’s advantage over relegation-threatened Burnley to remain 11th in the league standings. It was the fifth match in a row that Chelsea conceded two goals. “The changing room is really down,” Palmer told Sky Sports on Saturday. “When they went down to 10 men, we were 1-0 up and just got too comfortable. Same story, we kill ourselves every week. It’s got to improve from us as players. “We had many chances and then that time we defended sloppy. It’s very disappointing. On a personal level it’s good to score two, but if you don’t get the three points they count for nothing. “I think it’s our consistency all around the pitch, being alive and not switching off like we did today. It’s poor, it can’t happen. Especially when they go down to 10 men.”
