Manchester United could have a mass exodus if they fail to qualify for the Champions League.
United is currently sixth in the Premier League on 64 points and they no longer control their own destiny.
David de Gea, Paul Pogba and Romelu Lukaku will all consider their futures if United is out of the Champions League.
United received a bid from Barcelona for Pogba when he and Jose Mourinho were at odds.
De Gea has yet to agree to a new contract and that prospect looks remote.
