Sheffield Wednesday have struggled to score this season and will be expected to add more attacking quality next term.
The Owls are the fourth lowest scorers in the Championship and not one of their players has managed to get into double figures this term.
It means that they have struggled to pick up victories on a regular basis this season, and Gray's comments would suggest that he will be looking to make big improvements to Wednesday's attacking ranks over the summer.
"Where we have let ourselves down is in front of goal," he said. "When I evaluate at the end of the season, I will be thinking we could have been a lot higher if we had converted our chances. We have to improve and look at all aspects. It is not just on the pitch. It is off the pitch where we (also) need to improve.”
Wednesday will be among the favourites for promotion next season and it is obvious that they will need to be more threatening if they are to achieve their aims.
The Yorkshire outfit have managed just 41 goals in 44 games this campaign, with their struggles leading to them becoming lodged in mid-table for the most part.
For this season that has been fine, but with Gray set to be backed with funds following the takeover of Dejphon Chansiri, expectations are rising around Hillsborough.
It means that big improvements will need to be shown next term and Gray will be hoping that he is the man to deliver the success that the Owls so desperately crave.
