Valencia are working on signing Super Eagles striker Sadiq Umar when the transfer window reopens next month.
According to Marca, Valencia are working to reinforce the team in the winter market to prevent a significant decline in performance in the second half of the season.
The club have resumed conversations to sign Sadiq, after not reaching an agreement with Real Sociedad in the summer.
The player would also like to return to Mestalla.
The forward has 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.
