Odegaard has same number of assists in the league as Bruno...but Bruno didn't take all the dead balls, Eriksen had quite a few before his injury thus Eriksen has a strong assist numbers.
But Bruno also has a high amount of assists unrealized because outside of Marcus, nobody has been able to score at even a decent clip as a forward player. Arsenal have 25 league goals between Saka and Martinelli, and 5 from Jesus. That's 30 for those counting at home and then Odegaard has chipped in 10 goals. So between those 4 players, that's 40 goals.
Bruno (5), Martial/Weghorst (3), Antony/Sancho (7), Marcus (14)...that adds up to 29 from 6 players.
Long story short, Bruno is not a glaring issue. Issue has always been a reliable and above average center forward/striker to share the goal scoring burden with Marcus. To supplement his 14 league goals with at least 10 by now...United would be much, much closer to Arsenal if not ahead of City. But alas, this is where United are.
Shit, if United had Cavani from his first year with United under EtH's first season, United would be in much, much better shape.
