Manchester City boss Pep Guardiola has confirmed he is interested in signing Everton defender John Stones, reports BBC Sport.
It is thought Everton want £50m for the 22-year-old, who came close to joining Chelsea last summer.
"Everyone knows we are going to try," said Guardiola after Thursday's friendly win over Borussia Dortmund in China. "We will see what happens."
Guardiola added: "I am very happy with the squad we have."
A deal is yet to be agreed but it is thought the two Premier League clubs are not far apart in their valuations.
