Manager charged with change, Harlow's ending season last in table (6,12)

'manager charged' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'with change harlow's ending season last in table' is the wordplay.
I cannot quite see how this works, but
'with' could be 'w' (short for with) and 'w' is located in the answer.
'change' could be 'alter' (synonyms) and 'alter' is found within the answer.
'ending' could be 'win' (win is a kind of ending) and 'win' is located in the answer.
'last' could be 't' (I've seen this in other clues) and 't' is present in the answer.
This explanation may well be incorrect...

Can you help me to learn more?
