The out of contract star may be seen as the ideal stop gap signing for Manchester United.
Per Mundo Deportivo, the Red Devils are assessing the 32-year-old as a summer signing.
United have injuries in defense and have lost new signing Leny Yoro for three months.
While they are pushing to sign Bayern’s Matthijs De Ligt, Hermoso would be a much cheaper alternative.
The issue is that he is demanding a multi-year deal worth a gross salary of €6 million.
