Jose Mourinho stated that he doesn't know if Manchester United will back him with reinforcements over the winter transfer window. 

“I don’t know if we are going to have new players – I would like to – but I don’t know if it is possible or not. It depends on the club,” Mourinho said. 

 

Mourinho has been especially vocal about his desire to upgrade at the center back position, with Napoli's Kalidou Koulibaly a frequent target of rumors.
