John Stones has reportedly been put up for sale by Premier League champions Manchester City after falling down the defensive pecking order.
The England international is now seen as fourth-choice at centre-back behind Vincent Kompany, Nicolas Otamendi and January recruit Aymeric Laporte.
City boss Pep Guardiola has praised Stones publicly this season but, according to The Sun, he is after a different type of central defender this summer and the 23-year-old is the odd man out.
Guardiola does not feel that the ex-Everton ace has improved sufficiently during their two seasons working together, it is claimed, and the Citizens will look to recoup as much of the £47.5m laid out to sign him as they can.
Top-flight rivals Liverpool and Arsenal are among the sides said to be weighing up a bid.
