West Ham have jumped to the front of the queue for Blackburn striker Ben Brereton Diaz.
The Sun says Hammers boss David Moyes sent spy Alan Irvine to watch Rovers' top scorer who is going into the last year of his contract.
Brereton notched his 22nd goal of the Championship season against Birmingham on Saturday.
And that form has seen Chile international, 23, attract the Hammers' attention as Moyes looks to add more firepower.
Brereton will cost around £15million but his versatility, playing wide of a three and through the middle, appeals to Moyes.
But the Scottish boss is facing a lot of competition to land his man.
