Agreed on Lindelof, he's about as cowardly defender as I've seen at United. Bailly for all of his faults showed against Chelsea what's needed in there next to Maguire, if he can stay fit and kick on I think he'd be a pretty great answer to that problem. Of course, chances are injuries will make that impossible.
Solskjaer too might not be a good enough manager to take us to the top but I like what he's doing with regards to squad building, so that's a tricky one really. As ridiculous as it sounded at first, maybe a DOF role wouldn't be the worst idea if he keeps it up but proves to be a sub standard coach. Who knows.
And maybe Greenwood could be the answer to the Martial issue in a year or twos time? His talent is beyond question I think, and he seems to have a pretty good mentality. We've got enough holes in the squad to fill over the next 3 or 4 windows to give him some time to develop, in which time maybe Martial could even find some consistency?
Lots of questions still to be answered, but I like the way the squad is shaping up for the first time in a long long time, so that's a bit of a silver lining.
