There are certainly question marks around our midfield. As someone who has very much defended Pogba as an individual, I wouldn’t dismiss the question posed out of hand.
I think he’s a great player, but signing Bruno was the problem for me. At the time, I thought it was the wrong signing in terms of what the first team had and lacked. There had been a lot of talk of Grealish, and with Pogba having been out injured for most of the season and the lack of creative quality in midfield without him exposed, I thought that the mandate was to look for cover for Pogba. I thought Grealish would come in as a creative back up for him, much as he is being linked with coming in as a creative back up for Bruno now. But for the first team, I remember saying loads in January that I was confused as to why we were not targeting a proper central midfielder like Saúl, to come in and play WITH Pogba and a DM like Matic or Fred. That would have given us the best midfield balance I think.
That said, we opted to sign Bruno, as a starter. This changed the structure of our FIRST CHOICE midfield. Perhaps Ole did not feel Pogba would stay, I don’t know. But he went for a first choice 10, when, if he was intending to have Pogba as a regular fixture in his midfield, the team would have been better served with him spending big money on a first choice 8 instead. A player like Thiago perhaps. That would have increased the quality of our first choice midfield by still removing Lingard/Pereira from the XI, but replacing their role as chief creator with Pogba. McTominay would have then been significantly upgraded with a better version of himself. In terms of quality, we are superior to before lockdown, but inferior in terms of balance in midfield.
Anyway, having Bruno in the team, I think there is now certainly scope for a different type of midfielder to Pogba to be signed instead. Ole has created a situation where it is definitely now valid to ask whether we should sell Pogba, although it wasn’t a necessary situation 8 months ago in my opinion - but we are here now. What he essentially did in January was look at whatever he thought our first choice midfield was, and sign a replacement for the best one of them in Pogba. Structurally, I think that was the wrong call, and to properly validate it, he needs to go and buy another midfielder to now play with Bruno, one who is better defensively than Pogba. Otherwise it will just be McTominay and we’d be no better off than if we had signed nobody in January. We’d just have swapped creative midfielders.
The player that I image the OP wants to come in instead of Pogba is the player we should have bought in January. I don’t think Bruno is a significant upgrade on Pogba as chief midfield creator, if we stick to the facts and not feelings. He is a far better penalty taker, but other than that, I don’t think he has a better final pass, dribbling or goalscoring, in terms of open play, from what I’ve seen. He’s a fine player, and I have no qualms with him, but I don’t think he’s the midfielder we needed most- IF Ole was still harbouring hope at the time that his future midfield would include Pogba as a key cog. If he felt Pogba was leaving, or he wanted to buy him as back up, then it makes more sense. Pogba in a double pivot isn’t optimal really. And I agree that, with Bruno in the team, we’d be better off with say Thiago or Saúl instead of Pogba.
This is not me trying to have a dig at Bruno either. It is almost the same sentiment as if we had gone and signed Manuel Neuer while De Gea was at his peak. Neuer is of course class, but it creates a problem/question regarding De Gea, as they should be competing for the same role. Unless De Gea was going to leave, we’d have been better off buying a LB or something with the money instead!
