Have to say I'm stymied and all of your suggestions have been amazingly helpful. Sort of 'oh, of course' helpful. Though I know nothing about football and would never have got that one.
Now I'm stuck in the bottom left corner. Maybe if I just solve one of them, the rest will come. So -- 15a: enthusiast with excellent muscle tone. (4). I have none of the letters. So a clue please?
Thanks.
