Manchester City are eyeing Villarreal defender Pau Torres.
ESPN says Torres is an option for bolstering City at the heart of the defence.
Pep Guardiola will prioritise signing a new central defender ahead of landing the left-back.
Benjamin Mendy and Oleksandr Zinchenko have both had fitness issues this campaign while Angelino did not make an impact after signing last summer and was loaned to RB Leipzig in January.
Leicester City fullback Ben Chilwell, who has also strongly been linked with a move to Chelsea, has been monitored by City but the Blues are prioritising strengthening in other areas.
