Gordon and Isak are significantly better at their jobs than Antony and Hojlund. Swap our frontline with Newcastle's and you'd see Bruno register a lot more assists.
Gordon plays on the left, but yes, he is better than Rashford, but he also works incredibly hard and isn't a selfish player like Rashford. Your second point is just an assumption, and it's something you don't really know. Bruno has played with great attackers during his time here, but has never really had exceptionally great assist numbers here. Isak, Almiron or Gordon has never scored as many PL goals during a season as Rashford, either.
Isak and Wilson have missed 5 big chances each this season, which is 3 more than Højlund and Rashford combined. It's not like their attackers score every chance.
Again - to be a succesful team, you need a player who's creating chances and taking risks on the ball. Newcastle have a workman-like midfield and rely on their RB to provide the creativity, much like Liverpool relied on Alexander Arnold when they won the league. Henderson and Wijnaldum did their jobs in providing the stamina in midfield, however if they had a RB with the limitations of Wan Bissaka then they wouldn't have won the league.
Those players should primarily be the attackers, not our midfielders. If we're going to take up one of our midfield spots on a chance creator, he better have an exceptional set of skills to go with it. Unfortunately for us, Bruno is quite limited and has a lot of weaknesses.
Take out Trippier from that Newcastle team, and they've still scored much more goals than us. No team relies only on their fullbacks for creating chances. Anyway, since there are fullbacks that are able to create more chances than Bruno, do you not think it would be a better alternative to use a fullback to be responsible for that, rather than a midfielder who has several weaknesses?
By that logic, because we weren't winning league titles in the 80s, we should've sold Bryan Robson then?
You can't just apply that argument to any player. Bruno is very easily replaceable. Bryan Robson was an uniquely brilliant player.
You seem to have fabricated this idea in your own head that Bruno is giving the ball away on the edge of his own box. If that's the case, give me examples of goals we've conceded as a result of this. De Bruyne and Bruno both give away the ball in similar areas.
Not really outside our own box, but he often does it on our side of the pitch, or around the midfield circle. It's not necessarily the passing I'm referring to, either, but it's him losing the ball because of a slight push, bad touch, or just wanting to get rid of the ball because he has no dribbling ability and as soon as he is pressed, the ball is theirs. De Bruyne doesn't lose the ball nearly as easily as Bruno, even if their pass completion rate is similar. A good example would be to watch the Bruno vs Atletico Madrid compilation YouTube, and you'll get the idea what I'm talking about, and how he loses the ball.
