Dusan Tadic, Michy Batshuayi and Kelechi Iheanacho are the top priority for West Ham United in the upcoming transfer window, according to The Sun.
Hammers' boss Slaven Bilic has insisted he will be active this summer, having already made his first signing in Manchester City's Pablo Zabaleta on a free transfer.
Zabaleta's former teammate, Iheanacho, is reportedly available for £20m after falling behind Sergio Aguero and Gabriel Jesus at the Etihad.
Tadic, 28, has been a consistent performer with Southampton over the past three seasons, and is reported to be worth £15m.
Chelsea forward Batshuayi is believed to be available for a loan spell, with Monaco, Marseille and Newcastle United also showing interest.
