Zirkzee said: "Having had discussions with the manager and the leaders of the club I know how exciting the future is going to be here and I cannot wait to play my part in achieving success for Manchester United. "I am a player who has always dedicated everything to winning; I'm ready for this next challenge, to go to another level in my career and win more trophies.
