Showing weakness, pay price to football club and lay low down here (4,2,4)
I believe the answer is:
feet of clay
'lay low down here' is the definition.
The definition suggests a singular noun which matches the answer.
'showing weakness pay price to football club' is the wordplay.
I cannot quite see how this works, but
'pay' could be 'fee' and 'fee' is found within the answer.
'to' is within the answer.
'club' could be 'y' (YMCA or YWCA commonly shortened) and 'y' is located in the answer.
This explanation may well be incorrect...
'and' acts as a link.
Can you help me to learn more?
(Other definitions for feet of clay that I've seen before include "lepidopteran floaters, once?" , "Shaky supports" , "may make you slip in wet weather?" , "Fatal flaw in an otherwise admirable character" , "Flaw in an idol" .)
