Mitro's On Fire But How Much Has He Improved?

As reported by The Chronicle, Aleksandar Mitrovic has taken his tally to seven goals in six games following his header against Wales last night.
Mitrovic is only two goals behind his overall tally of ten goals last season. Impressive considering, he has not been a regular for Newcastle this season.
Mitrovic also seems to have learned to channel his energies in a positive way and notably has no red cards in black and white this season.
When all of this is taken into consideration, it is safe to say that Mitrovic is improving, seemingly on a weekly basis, but just how much is he improving?
Despite his impressive goal record, it must be remembered that for Newcastle he is playing at a lower standard than he was last season. However, this is not the case for Serbia and his discipline is improving despite playing at a more physical level.
Mitrovic also looks more athletic, covering ground quicker, and while we will not know just how good he is until he is back at the top level he has been linked with moves to some top sides.
Furthermore, consider this, if Newcastle had this Mitrovic at their disposal last year, would they have survived? With Jermain Defoe almost single handedly keeping Sunderland up and considering how close Newcastle were to survival despite not having a goalscorer, I think there is a good chance that they would have survived.
Time will tell just how much Mitrovic has improved but he is still young and I for one feel as though he has a big future in the game. It is certainly a positive that he seems committed the cause at Newcastle and it may not even be long before he overtakes Dwight Gayle as first choice striker at the club.
