I'm actually not sure he's done a bad job in the parts he's actually done. The problem has been he's let others make big decisions and they've been expensive mistakes
At the moment i'm only willing to have Sandro be a mistake - and that was a limited cost one.
I think, after stewing on this some more - it's the stuff he *hasn't* done that has me questioning him.
Left back, width, pace, main striker. Leaving the summer window without that was bad.
Leaving the jan window without 2 of those things still seems indefensible.
If Mangala was genuinely an option at left back then i'll forgive the lack of immediate main striker and happy to give him another window now that @brap2 has made that point.
If he wasn't then i want him out as 2 windows should be sufficient to fill any 1 position.
