The Newcastle United striker will come good in time, but only if he has the faith of his new supporters.
The 20-year-old had already scored 68 senior club goals before he arrived at St James’ Park, including 43 in 89 matches for Anderlecht, 18 in 42 for Partizan Belgrade and seven in 26 for Teleoptik Zemun.
But along with those goals Mitrovic had also collected 37 yellow cards and four red cards, ensuring his reputation was often described with the word ‘temperamental’ thrown in.
And so it has proved in his early days at St James’ Park, where he is yet to score but has already picked up two bookings and one straight dismissal.
As a result it would be easy for Newcastle fans to get on his back and to bemoan why manager Steve McClaren opted to sign the young Serbian rather than Queens Park Rangers’ Charlie Austin or another player proven in the English top flight. But that would be a mistake on the part of the Magpies’ fans.
Whoever they feel should or should not have been signed this summer, their squad has now been confirmed until at least January. And in Mitrovic they have a player who has all the traits needed to become a goal-scoring superstar in the North East…but only if they allow him the time to settle.
Yes he will have to learn to calm his temper on the pitch, but in part that is what makes him the player he is so the trick is maintaining the attitude but losing the impetuousness.
Newcastle supporters can also play their part, ensuring they do not voice their frustrations so soon after his arrival.
After all, Mitrovic is young and has only just arrived in the country, but in time he could be the most prolific goal-scorer Newcastle have had since Alan Shearer.
