West Ham have made a bid for Dario Osorio
Universidad de Chile legend Johnny Herrera reckons that the Hammers, as well as Leicester, have already made a concrete offer to bring the 19-year-old forward to the London Stadium.
“One of the majority shareholders (at Universidad) told me that (an offer) came of £5.5 million arrived from West Ham. Now, one from Leicester for £6.7 million as well. “I know of two offers for Osorio. One last year and this one from Leicester.”
