Chris and Gabby Adcock were knocked out of the All England Open at the quarter-final stage by top seeds and Olympic champions Zhang Nan and Zhao Yunlei.The husband and wife team were beaten 21-10 21-13 by the Chinese pair.
"I don't think they played anything special today but our performance was very below par," said Chris.
"We beat ourselves. We've had patches of being really good and patches of being not so great. Quarter-finals are OK but that's not what we're here for."
The England pair had beaten Zhang and Zhao in the semi-finals on the way to their Hong Kong Open triumph in November, but that remains their only win against the Chinese top seeds in six previous meetings.
Friday's defeat was Chris Adcock's second by Zhang in 24 hours after losing to him in the men's doubles on Thursday.
