(Reuters) - 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.
