He's a workhorse but I don't see him ever being prolific.
There aren't that many "prolific strikers" around in the premiership mate. Think if he can give us 10/15 a season once he's more established and experienced, I'd be happy. His all round play will also create goals for others and would have a lot more than his current 4 assists if certain people were able to convert all the penalties he wins.
His goals are comparable with other strikers within his age group (Rashford, Abraham, Solanke) who get game time in the premier.
He's got a lot more development to go through before he can be considered a regular starter in the premier, but with the right management I believe he has the attributes and the attitude to do so.
He's been thrown in the deep end this season in a poorly performing team low in confidence, and most often played out of position. But I believe he's risen to the challenge and, together with Holgate, has been the most improved player in the squad. He's never shirked a challenge or hidden, unlike most of our more experienced players, and I wince sometimes when I read some of the stick he gets in this thread.
I agree that he'll never be prolific (regularly scoring 20+ per season) , and it's possible he may not even make a career here. But at this moment in time I'm more than happy with his development, and just wished that everybody just got behind him, and all our other youngsters for that matter, because if we can keep this group together I believe we WILL be pushing the 6 teams above us within the next couple of years.
