New Spain coach Luis Enrique is keen to be reunited with Juan Carlos Unzue.
The former Barcelona boss was named La Roja coach on Monday.
And AS says Unzue is being lined up to work as assistant coach to Enrique.
Unzue left Barca a year ago to take charge of Celta Vigo, but was relieved of his duties last season.
Enrique and Unzue were together for three years at Barca.
