Manchester City boss Pep Guardiola plans to overhaul his squad this summer.
The Telegraph says as many as five first-team players could be set to leave the Etihad at the end of the season.
Attracting interest from City is Villarreal's Pau Torres, 22, who made his Spain debut in November.
He could arrive at the Etihad as a replacement for Nicolas Otamendi, who has been far from convincing this season.
Further up the pitch, 34-year-old David Silva is calling time on his Etihad career after entering his tenth season at the club. Leroy Sane is likely to be sold once he recovers from a cruciate ligament injury.
There could also be a change in attack, with City apparently unsure over Gabriel Jesus' future
