Manchester City are eyeing Valencia fullback Jose Luis Gaya.
The Sunday Times says City are desperate to draft in younger full-backs.
Gaya is contracted to the La Liga outfit until 2020.
But the gifted left-back does have a £45m release clause that City could activate.
Pep Guardiola already has four senior full-backs on his books - Gael Clichy, Bacary Sagna, Pablo Zabaleta and Aleksandar Kolarov.
And despite the talent already at his disposal, the quartet are all over the age of 30.
