Head of Football League stopping team getting debilitating illness (3,3)
I believe the answer is:
man flu
'debilitating illness' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'head of football league stopping team' is the wordplay.
'head of' suggests taking the first letters.
'stopping' indicates putting letters inside (inserted letters stop or plug a gap).
'team' becomes 'Man U' (short for Manchester United).
The first letters of 'football league' is 'fl'.
'fl' inserted inside 'manu' is 'MAN FLU'.
'getting' is the link.
Can you help me to learn more?
(Another definition for man flu that I've seen is " Overstated complaint".)
