#4 Anthony Martial - Manchester United

Anthony Martial shouldn't be known for his relationship with Jose Mourinho, but instead his immense potential.

Anthony Martial has had a roller-coaster of a time at Manchester United. Working under Jose Mourinho has taught him a lot, but those lessons have been bittersweet, to say the least. Mainly, he has learned from his mistakes - most of those evolving from his relationship with Mourinho.

The media is consistently on their case, as football fans across the globe seem fascinated by their constant tiffs. It remains to be seen whether or not this will sway Martial's decision to sign a contract extension.

Watching him on the ball, it's easy to feel excited. He consistently pulls new tricks and flicks out of the bag, while his speed off the ball is electrifying. He's shown glimmers of hope, but nobody knows whether or not they warrant a new contract.

One thing's for sure, the Mourinho curse looks likely to strike should Martial move elsewhere.
