"I have always wanted to play in the Premier League and to join the biggest club in the world is what every young footballer dreams of. I am looking forward to meeting my new team-mates and working with Louis van Gaal who has achieved so much in his career."
Louis van Gaal: "Anthony is a naturally talented, young, multi-functional forward with great potential. We have been watching him for a while now and he has developed immensely during his time at AS Monaco.
"I am delighted he has joined Manchester United as I believe this is the right club for him to continue his development as a young player. He has all the attributes to become a top football player; however we need to give him time to adjust to his new environment and the rhythm of the Premier League."
