West Ham United boss David Moyes is chasing after Manchester City defender John Stones.

The Englishman has endured a difficult campaign at City, riddled with injuries and a loss of form.

With City set to sign defenders, including Nathan Ake from Bournemouth, Stones may be surplus to requirements.

The Sun says Stones is likely to leave for roughly £20 million.

It has alerted Moyes, who worked with Stones at Everton.

Arsenal also have interest, but may have to sell players before they can buy.
