Manchester United defender Marcos Rojo has reportedly impressed Ole Gunnar Solskjaer in preseason training.
The Argentine is up for sale after spending the second half of last season on loan at Estudiantes.
ESPN states United are having trouble selling their fringe players, including Rojo, due to their high wages.
Rojo and Chris Smalling have been told they will be given a chance to impress during preseason.
And Solskjaer has noticed the extra work put in by Rojo, with the 31-year-old training twice a day.
Smalling, Phil Jones, Andreas Pereira and Sergio Romero are the other players United are willing to let leave.
