Sadio Mane
The Southampton attacker was subject to a move by Manchester United in the summer but was kept in the team by Ronald Koeman. That all could change in the winter window if Jose Mourinho does pick up the reins. Mane is the winger that could well change the attack of Manchester United and the 23-year-old Senegalese would be willing to make a move away from the Saints, if the price is right though.
