West Ham may be set for a fierce battle in the transfer market to retain the services of their key players, as intriguing reports have surfaced.

The Sun states new Everton boss Marco Silva has targeted West Ham’s Player of the Year Marko Arnautovic as an ambitious target for the summer window.

Arnautovic, who is also reportedly being tracked by Manchester United, arrived at the London Stadium for a club-record fee from Stoke City last year and played a crucial part in the Hammers push to avoid relegation.

The Austrian international netted 11 goals to save West Ham from the drop in his debut campaign at the London Stadium and Silva believes he’d be the perfect addition to lead his line on Merseyside.

Everton, backed by the wealthy Farhad Moshiri, are seemingly ready to go all-out to land the 29-year-old with an approach worth a reported £50m – double what the Hammers paid last summer.

West Ham are determined to retain the services of their prized asset but may find it difficult to reject such a mammoth offer, especially when Pellegrini is eyeing significant business of his own.
