Arsenal let another lead slip as a Petr Cech error gifted Crystal Palace a 1-1 Premier League draw at the Emirates.
Alexis Sanchez planted a header past Wayne Hennessey at the end of an otherwise featureless first half to give Arsenal the lead.
But Yannick Bolasie earned a share of the spoils on 82 thanks to some poor Arsenal defending – first Francis Coquelin failed to close the Palace winger down, then Cech failed to keep out his low shot at the near post.
The result came after Arsenal surrendered a two-goal lead in last weekend’s 3-3 draw at West Ham.
They failed to reclaim third place from Manchester City, who won at Chelsea on Saturday, and now sit just four points ahead of fifth-placed Manchester United.
