Beginning to think we need to move on from him to progress. In the meantime, he should be playing either side of the striker because having him in the midfield three is effectively having us play with only 2 in the middle.
Of course we do. You can't have a Lukaku or even a Haaland in your midfield 3, whose contribution is based on output. You can just about get away with that for a centre forward, and even then, not always. It takes one kick of the ball to score a goal or create one. Any player can score a goal or give a pass but every player has to first come with a set of fundamentals. Especially midfielders. You cannot be a midfielder who only brings cherries to a cake. Too much of a football match is spent not in the action of scoring or creating a goal. First and foremost - what do you do? How do you contribute to the function of this football team? Once we establish that - we can then differentiate between even top footballers by productivity, but as a midfielder, you cannot skip that part and go straight to the 'I score goals' part as your contribution.
When building a team, you have to first think what you want that team to look like and how it should play. Then you add players to that, and the hope is that if you can get your team playing how you want, it will also create and score goals. And if it isn't, then you look to improve pieces within that team that can give greater productivity. In signing Bruno, Ole tried to bypass any team building foundations and just get a player to put the ball in the net. Which is a recipe for top 6 or 4 at best, but not to be the best team over 38 games. And even then, it only makes sense if we're talking about a centre forward. Bruno is just too poor (or average, to be kinder) at too many things which cannot be ignored if you still want to maintain that you are any sort of 'midfielder'. He has no outstanding qualities of a midfielder apart from an ability to sometimes play an outrageous pass. No turn, no acceleration, no strength, no composure, no dribble.
This 'he's always poor in the big games' is not down to lack of mentality or anything. It's solely down to lack of ability. These games are simply 'too hard' - all the individuals he comes up against are too strong, too quick and the units are too well set. That is where the elite find ways to still impose themselves on games - but against such opposition, it's a step too far for him to have any real foothold. Of course, if he plays 50 big games, he will still have moments, there will be the odd goal or assist - but there will NEVER be a 'they just couldn't live with Bruno Fernandes today' the way we could say against the likes of Silva, De Bruyne, Modric, Verratti, Scholes and basically any top level midfielder.
In all my years watching football I don't think, off the top of my head, that I've seen another midfielder who needs to have affected the scoreline to be considered to have had a good game. Yet for too long I came here after games to read 'wasn't great, but still got an assist'. Bruno seemed to just want to come off the pitch having 'got his goal' or got his assist for the game. That is for strikers. He needs to first concern himself with whether or not he played well, helped the team play well etc. Said for years but I'd happily swap his '28G/25A' for 10/10 a season if it came with an actual midfielder who is class at the fundamentals of football, and I suspect we'd be a far better team for it too.
