For me he's got till the end of the season at least. A lot of people are saying it's not great right now, yet we are only 2 points off 1st with a game in hand. That may well change this weekend against City, but I don't see how we can sack a manager when we are seemingly still in the running for a title challenge. If we go on another run like when he took over, or during the lockdown period, we will be right up there, so it feels ludicrous to say we should be sacking a manager already.
I accept there are some glaring problems. We need to seriously and quickly improve our home form plus our poor starts to matches. We've had games this season where it looked like we'd start well, only after 5-10 mins we dip back into the same mistakes/routines, even the Spurs game the initial start was lightning, then we left it behind us. The fact we seem incapable of having a good or even solid first 45 minutes to a match is worrying. But this is a relatively recent problem so I don't see why we can't fix it.
Also, I remember at some point there was talk of 3 windows with 3-4 signings in each, 8 or 9 players needing to be added if I remember? So far we've arguably had 6 of those additions. I'm discounting Cavani in that as to me is a short term option, and not part of that original plan. I'm also ignoring both Diallo and Pellistri, they both look like youth signings, not immediately part of the senior squad.
Whether that plan involved a replacement for Pogba, or he wanted to keep him at the club, I don't know. If we say 9 including the replacement, we are looking at 3 more signings. Some of the performances this year, bearing in mind we are supposedly 3 off having a complete squad, are absolutely concerning. I can understand why people are worried. But the mistakes we are seeing can't simply be put down to the manager, I personally can't just pin the current issues on him, there is more to it than that, the players, coaching staff, and Ole all take blame on that which is why I give him time to fix whatever has gone wrong.
