Your riposte is laughable, really.
He is a defender first and foremost.
If he cannot do the basics of defending (i.e. at least being positionally aware) then he is not doing his job properly. Who cares if he can do overlaps and push forward well, if cannot do the job that he is in the team for? Moving forwards as a fullback is a bonus. Not essential, like making sure the wingers are kept in line.
To make an excuse that Mellis wasn't tracking back is weak, if not completely nullified by the fact we were playing 4-3-3. Using that formation we will always by liable to a quick counter attack, particularly on the wings and therefore at the beginning of the game Harding knew what his responsibilities were. To get dragged so far centrally was such a basic schoolboy error once, but to do it again and again is just amateur.
Mellis was extremely poor, there was no denying that. But to take the blame away from Harding is in my opinion utter rubbish.
If you look at the way many of goals have been conceded this season it isn't through the central areas, it is down the flanks. Harding has played every single game, and yes, in some games he has been impressive. But in others he has been defensively naive.
This is my opinion though. You are entitled to yours also. But don't come on here an attempt to belittle me and spout off. Your opinion is no greater then mine.
In my opinion, Harding has been excellent in some respects. But in others, particularly his positioning, he needs a bit of coaching, or we will get over run again and again down our left flank.
