Could be and I'd be delighted to see Bruno and Pogba rip it up together, maybe against teams in the bottom 6 it will happen.
I just don't think we are strong enough defensively to accommodate both of them. One of the main reasons we've been solid defensively is down to Fred's incredible form and box to box energy, and the experienced streetwise positional sense of Matic to mop things up next to him. Without those two building a barrier infront of the defence, I think Lindelof might get targeted again by powerful opposition forwards, even though he's been playing very well also lately. But against teams in the top half of the table, I don't think defensively we would cope with both Bruno and Pogba in a midfield 3.
The combination of Pogba-McTominay-Lingard/Pereira happened from the first game of the season, against Chelsea - not cannon fodder. As disappointed as you were by that composition, Solskjaer continued with it until he was forced into a change with Pogba’s injury.
Sure, after Matic was initially brought into the team as his replacement, Fred established himself in the side. Then, when McTominay got injured Matic also established himself in the lineup at the second time of asking. I think it’s fair to say that both have done well and will be held in higher regard by the manager now than they were coming into this season.
It would have been interesting to see Solskjaer’s team selections from where we left off with McTominay back and Pogba on the way. At this point, we can’t be sure what the pecking order would have been or is. But you seem to be very confident you know, for some reason? Any talk of how well the others have done recently can be countered with the fact that when all four were available Pogba was a first-choice selection. He is also by far the biggest name, the most expensive asset and the highest-quality individual in that group. Although, as I said, no-one can be sure because the suspension of play stopped us from finding out, I would think it more likely that, if he’s still in the squad when everything starts back up, Pogba will be restored to the starting eleven. And not for games against the weakest teams in the league or to rest Fernandes - as a clear first choice option for one of those central midfield roles.
Although I would agree that our first choice pairing at the beginning of the season wasn’t quite up to scratch, the reason for that is because Pogba was being far too careless in possession. Defensively, there was no issue with either player. Our biggest issue in that respect was with the structure of our front four - the quartet constantly lost balance and took themselves out of the game by allowing the opposition to progress forward through full backs and the rest of the side had to adjust and attempt to stem the advancement and regain some form of control. In fact, Pogba in particular at the start of the season was covering across to help the full back more than any other player - with both Maguire and McTominay pushing over and allowing Shaw to challenge the opposition right back or confronting the player himself, respectively, and Lindelof scared of moving out to support on the right side.
The main reason we have been solid is because Rashford has been injured. For almost the entire season he has been free from the task - typically and naturally given to the wide attacking player - of tracking the full back on his side. This greatly contributed to and exacerbated the problem I have just described in my previous paragraph. Without a free role being afforded to one of our wide players in conjunction with the team pressing calming down a bit we are harder to play through. We settle into a much more secure shape much more often.
Pogba’s lack of proficiency in defending generally is often massively overstated here. He is not a liability, he is a willing defender but is not the kind of player who excels defensively - you don’t have him in that position, or in the team generally, for that. And that is the case in many sides both currently and historically - for every side that uses a more combative player alongside or closest to a holding player there is another that uses a player who excels more on the ball. Pogba operating there is not dissimilar to the likes of Scholes, Modric, Dembele, Eriksen, Kroos, Xavi, Arthur, Rabiot, Rosicky, Arteta, Edu, Cazorla, Fabregas, Pizarro, Toure, Banega, Verratti, Thiago, Gundogan or Sahin playing in that position. And not for select games, easy games, rotation purposes or anything like that - as bona fide starters in that role, selected for all manner of opposition and used consistently. The idea of using Pogba behind Fernandes with one other is in no way an unprecedented way to set up a midfield or team. There is nothing unconventional or experimental about it.
Posters who are concerned about our defensive solidity in such a set up rarely discuss or acknowledge the problems that using another one of our options there could cause or compound. We certainly want to be solid defensively but we also want to be able to effectively build the play and break other sides down. We also most definitely want to challenge for honours and be successful again, and that means the onus being on us to go and win games. Predominantly, we will be expected to be proactive and take the game to our opponents. I think that all of Matic, Fred and McTominay have certain good qualities when we are in possession, but all offer considerably less than Pogba in that sense.
I don’t think anyone can argue that Pogba and Bruno are our two best midfield players. I don’t think they are a perfect pairing and I don’t see any of the other three midfielders as a perfect compliment to the two of them either. My concern would be with their shared inclination for speculative passes - both are very positive players who can be relentlessly forward-thinking. They can force it, and will play risky passes and they won’t always come off. Pogba can make it work, positionally, as although his best position is probably as the most advanced midfielder with the most freedom to attack in a three - essentially the same as or equivalent to where/ how we have been using Fernandes - he does also thrive from the role in support of that more advanced player.
Ideally, as a pairing they would be best combined with someone who is safe and stable in their passing and positioning to offset the natural tendencies of both, and in truth we don’t have a player of those qualities. A set up can be perfectly good and can be your team’s best without being perfect though. I would make do with any of Matic, Fred and McTominay as the third midfielder as opposed to using any two at the expense of one of our two more creative guys, as I believe you gain more overall from having both Pogba and Bruno playing rather than two of our three more conservative, ordinary players. It is definitely in United’s interest to get both players firing on the pitch together, so I think it’s basically a certainty that we try this if Pogba is still here when a ball is next kicked.
