Give over mate, it's an opinion, you can define it as an 'agenda' if you want but make sure you do the same with every other opinion you encounter and form in your own mind.
DDG doesn't ever command his box, his distribution is mediocre at best, same with coming off his line. Added to that, his shot stopping heroics have begun to dip and he's massively overpaid.
Letting him go and bringing in Henderson is what I think Utd should do, it's my opinion, and I'm fine for you to disagree with it, but give over with the daft 'agenda' stuff, no-one's interested and it makes you look like a muppet and undermines your actual point.
