Best having ball on both United's wings? (5)
I believe the answer is:
outdo
'best' is the definition.
(I know that best can be written as outdo)
'ball on both united's wings?' is the wordplay.
I cannot really see how this works, but
'ball' could be 'o' (O looks like a ball) and 'o' is found within the answer.
'united' could be 'utd' (common abbreviation as in names of sports teams) and 'utd' is present in the answer.
A single letter 'o' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'having' is the link.
Can you help me to learn more?
(Other definitions for outdo that I've seen before include "Go one beter than, surpass" , "Perform better than (someone)" , "Beat" , "going to top?" , "Get the better of" .)
