The Germany international midfielder is facing the prospect of getting axed along with eight other United players according to the Sun.
Schweinsteiger was not included in the United squad that travelled to China either but that was down to being on his honeymoon.
The latest reports from the Sun suggest that the World Cup winner is on his way out over the summer.
Besiktas will be hoping United allow the midfielder to join as a free transfer or for a small fee considering the club are under the watch of FFP.
The full squad is as follows:
De Gea, Johnstone, Romero, Valencia, Darmian, Jones, Rojo, Bailly, Blind, Shaw, Herrera, Fellaini, Mkhitaryan, Young, Schneiderlin, Carrick, Mata, Lingard, Memphis, Ibrahimovic, Rooney, Martial, Rashford.
