But could the 21-year-old develop into the manager's most important player in time at the London Stadium?
Javier Hernandez scored twice as West Ham ended Newcastle's winning run with an accomplished 3-0 victory at St James' Park.
His positioning and reading of the game was excellent throughout, something which shows his maturity and he also has general Fabian Balbuena acting as a calming influence alongside him.
Newcastle had gone into the game on the back of three successive wins, but were undone within 12 minutes when Hernandez steered home Robert Snodgrass' cross, and all but beaten when he converted from Marco Arnautovic's flick.More news: Fortnite Creative Lets Players Design Games

Pablo Zabaleta got in a vital block on Salomon Rondon's stoppage-time effort, but Newcastle headed for the dressing room knowing they simply had not done enough during the opening 45 minutes.
"Javier has always been a very important player for us". On Saturday, the Magpies welcome West Ham to St. James' Park, with one team looking to move ahead of the other in the table.
This was the first of seven Premier League matches in December for West Ham and a sizeable points tally will be expected.
The first major concern for West Ham will be the injury status of their forward Marko Arnautovic. "Attacking, we scored three goals and we created a lot more chances and defending, we kept a clean sheet and really Newcastle didn't have clear, clear chances".
West Ham's Javier Hernandez has scored 48 Premier League goals with all of those strikes coming from inside of the box - only Tim Cahill (56) has scored more goals in the competition with 100% of them coming from inside of the box.
Anderson's pace down the left caused Newcastle all kinds of problems, but it was Mexico worldwide Hernandez who put them to the sword.
