Martial's goal against Newcastle will cost Manchester United £7.2 million

United paid £36 million to Monaco while buying Martial, and the value could potentially go up to £57.6 million if certain clauses are met.

Among these clauses, was the one where they had to pay £7.2 million if he scored 25 Premier League goals.

Other clauses would get triggered if he makes eight more appearances for France and/or win the Ballon d'Or by 2019.

It is hard to believe that given the talent Anthony Martial posses, he was not able to score 25 Premier League goals sooner.

However, he has hardly been used by Manchester United.

Such a talented footballer deserves much more playing time than what he gets.

Martial has great speed, footwork, and shooting abilities and could become the next Hazard.

Martial, signed by Ed Woodward, is a valued asset for United.

Martial's contract expires next summer, with an option of an additional year.

But, he has told the board that he will only sign an extension if Mourinho is replaced by then.

Martial has hardly received playing time under Mourinho, and if the Portuguese manager stays, he will look for greener pastures elsewhere.
