Marouane Fellaini has told Sky Sports News he is waiting to see if he has a future at Manchester United under Louis van Gaal.

The midfielder endured a difficult first season at Old Trafford after former manager David Moyes signed him from his former club Everton for 27.5 million pounds.
And new manager Van Gaal has already signed one central midfielder, Ander Herrera, and is pursuing others.
There have been suggestions Fellaini will be allowed to leave and the Belgium international, asked if he will still be at United next season, he said: "We will see after the World Cup."
Fellaini scored Belgium's first goal in a World Cup for 12 years when he equalised against Algeria and has helped Marc Wilmots' side reach the quarterfinals, where they will face Argentina.
But he doesn't believe he has proved a point with his performances in Brazil, adding: "I don't have to prove [anything]: I've been a professional footballer for eight years."
Fellaini failed to score and only started 12 league games during an injury-hit first season at Old Trafford as United, the 2013 Premier League champions, finished seventh.
