Arsenal boss Arsene Wenger admits his side suffered a blow in their quest to win the English Premier League.
The Gunners could only manage a 3-3 draw away at West Ham United despite enjoying a two-goal lead mid-way through the first half.
The draw means leaders Leicester City are now ten points in front of Arsenal with only six games to go for the Foxes.
"We've shown resilience and spirit to come back to 3-3," Wenger is quoted as saying by BBC Sport.
"In the last 20 minutes it could have gone both ways.
"I'm disappointed we didn't [have an answer to Andy Carroll].
"I'm not here after the game to blame the players. We are disappointed to concede three goals. Particularly after 2-1. Overall it's a shame.
"Do we still have an opportunity to win the title? I don't know. We made it more difficult today."
