It's little wonder Graeme Jones was so keen to congratulate the striker and celebrate alongside him after the dramatic win over Fulham, for it's Newcastle's coach who has worked "tirelessly" with the youngster.
Osula was tireless in his 10 minutes on the pitch on Saturday. And direct. And impactful. And chaotic.
And as [Newcastle](https://www.thenorthernecho.co.uk/sport/football/newcastleunited/?ref=ed_direct) have shown on several occasions over the past few seasons, sometimes the chaos needs to be embraced.
Osula remains a work in progress but he is undoubtedly heading in the right direction. This time last season he'd played just eight minutes of Premier League action in two cameo appearances from the bench after his move from Sheffield United.

So far this term, there isn't a Premier League game he hasn't featured in. OK, there's been the odd 60 second cameo here and there where you might think it was hardly worth the effort to lace up his boots.
But there was also the goal against Liverpool, the double against Bradford in the Carabao Cup and the assist from the bench against Union Saint-Gilloise in the Champions League.
But his most meaningful contribution of the season so far came in the last minute of Saturday's game when he picked up the ball just inside the Fulham half and charged towards the away side's box with the type of intent the Magpies have too often lacked in the early stages of the campaign.
He did well to get a shot away and although it was saved, Bruno was on hand to turn home and score what Howe admits he believes could be a "mood-changing" goal.
Howe also revealed after Saturday's game that Osula has actually been nursing an ankle niggle, suggesting the striker would have played more had he been fully fit.
It all points to the fact that Howe has clearly seen significant progression in the striker over the course of the last 12 months.
“I just think there's been big growth in his game," said Newcastle's boss.
"He's worked tirelessly with Graeme Jones, who's done a lot of individual work with him - as have all our coaches, but Graeme in particular.
“I think the key thing for any player is when you come on the pitch regardless of what minutes you get, you impress, and I think Will has done that gradually and slowly, but surely. We've then trusted him with more minutes.
“Now, the ankle injury that he's got is slightly curtailing that because I don't want to make that problem worse, I want him to feel really good when he comes on the pitch, so we're sort of managing that. He's not 100% fit so we have to manage him correctly.
“But fundamentally his attitude – he wants to be here, he wants to play and he's very committed."
He almost wasn't still at Newcastle, of course. Osula was extremely close to joining Frankfurt on deadline day. That Howe was willing to let him go wasn't an acceptance of defeat with the striker, it was simply an acknowledgement that in the PSR era, £30m for a fringe figure - and that's what Osula was and remains, for now - can't be turned down
"I think you've seen, everyone that's watched us, a big development in his game and a big change in his confidence levels because of that," said Howe.
"He's coming on the pitch and influencing matches and he's got great attributes.
"He's worked tirelessly at his game since he's been here and I think we're seeing the benefits.
“Today, he did really, really well, I thought, to choose the right time to shoot. Leno's made a good save, but our captain is there to finish off the move, so it's a massive goal for us."
Were it not for Osula, Newcastle would have dropped more Premier League points. But he wasn't the only game-changer. Howe turned immediately to his bench after Sasa Lukic had cancelled out Jacob Murphy's first half opener 11 minutes after the interval.
At that stage, Fulham looked and will have felt the more likely victors but Sandro Tonali, who again started on the bench because of his recent illness, added control and Anthony Elanga provided speed and urgency when he was introduced soon after, even if the winger's decision making and final ball again let him down.
Then, against a tiring defence, Osula got the nod and immediately charged down Leno and panicked the visitors.
The striker will remain a substitute but no longer is he simply a bench filler, he's now an option and - as he showed on Saturday - a potential game-changer.
With victory on Saturday, Newcastle reached nine games having won three, drawn three and lost three, an identical record to the start they made last season. And that turned out alright for the Magpies...
