Valencia are intensifying effort to sign Umar Sadiq ahead of the January transfer window, DAILY POST reports.
Sadiq spent the second half of last season with Los Ches, scoring five times in 16 league appearances.
Valencia, however, failed in their bid to sign him on a permanent transfer.
The forward has one again struggled for regular playing time at Real Sociedad this season.
Sadiq has made just five league appearances for the White and Blues.
Valencia is desparate to bolster their attack after another underwhelming campaign.
They currently sit in 17th position on the LaLiga table.
