Jesus' finishing has been one of the main concerns - since the start of last season the 23-year-old has underperformed his Premier League expected goals tally by 6.97goals (in short, he has scored seven fewer goals than would be expected from the chances presented to him). In contrast, Haaland is overperforming by 6.83 goals since joining Dortmund, which is almost a 14-goal swing between the pair.
