West Ham United are launching a bid for Universidad de Chile winger Dario Osorio.
Osorio is expected to leave Chile for Europe this summer.
The 19 year-old is the subject of talks between Universidad and AC Milan.
However, The Sun says West Ham are making their move this week.
The Irons are to make an opening offer of €10m for Osorio and hope to wrap up a deal swiftly.
