I'm not sure we can rely on Gray to score the goals. He hasn't a league goal in 2022, and only 1 in the FA cup since Christmas.
DCL will score if fit often enough, but that's the concern.
No reason Gordon shouldn't improve again but he wasn't exactly prolific last season.
We would need to sign someone who can get double figures or 2 players who can get 6 or 7 each, and that's not straight forward. I wouldn't have much faith in us finding the right player, or couple of players. Teams who have 39 points and sell their main goalscorer, tend to be in a relegation fight again the following season.
