LONDON - The Premier League's most unpredictable title race has produced another surprise as Chelsea lost at Crystal Palace for the first time since 1990.
John Terry headed Joel Ward's cross into his own goal at the start of the second half to gift Palace a 1-0 victory, leaving Chelsea's position at the top precarious.
Chelsea's second successive away loss gave Manchester City a chance to go top by beating Arsenal.
Putting the pressure on City, Chelsea manager Jose Mourinho is publicly writing off Chelsea's prospects of lifting the trophy.
"We depend too much on other results," Mourinho said.
"When you depend a little it's possible, when you depend a lot, I don't think it's possible.
