Mikel Arteta bemoaned hapless Arsenal's inability to protect a lead as more squandered points left Liverpool in need of just one more to become champions for the 20th time.
Arteta's team led twice at home against Crystal Palace only to concede two equalisers and slide to their 13th draw of the Premier League season, nine times from winning positions.
Only Everton have drawn more and Arsenal, with four to play, are now a dozen points behind Liverpool, will win the title if they draw against Tottenham on Sunday.
