West Ham are eyeing Norwich City defender Max Aarons.
The Hammers are keen on the 21-year-old as David Moyes plans for the future amid their top-four challenge, reports the PA news agency.
Sky Bet Championship leaders Norwich – who made an instant return to the Premier League on Saturday – are likely to demand £30million.
Aarons was told last summer he would be allowed to leave Carrow Road this year and the Canaries are expected to keep to their word.
Norwich wanted to keep him to boost their chances of promotion after finishing bottom of the Premier League last year.
The England Under-21 international would prefer to stay in the south, in a blow to Everton's hopes of signing him.
