Every player who went further than the group stage at the World Cup is left behind but the 25-man party - who will play their pre-season in USA - is a strong one
The squad features 10 players who took part at the World Cup, including Wayne Rooney, as well as the club's summer recruits, Luke Shaw and Ander Herrera.
Shaw, David de Gea, Shinji Kagawa, Chris Smalling, Phil Jones, Juan Mata, Antonio Valencia, Danny Welbeck and Nani were all eliminated at the group stage in Brazil with their respective countries.
Of United's international contingent, only Patrice Evra, Javier Hernandez, Robin van Persie, Adnan Januzaj and Marouane Fellaini are not included, all of whom reached the second round or further.

Van Gaal has also included some younger players, with the likes of Tyler Blackett and Jesse Lingard given chances to impress.
