West Ham United have reportedly opened negotiations with AC Milan for striker Carlos Bacca.
The Premier League club have made no secret of their desire to sign at least one centre-forward this summer, with a number of names having been linked to the Olympic Stadium's new tenants.
However, after failed bids for a number of those options, Di Marzio has claimed that the Hammers have switched their attention to Milan's Colombia international.
The report adds that West Ham's opening bid was valued at around £15m, which the Rossoneri rejected.
Yet, it is believed that Milan are keen to do business and are likely to accept an offer in the region of £20m.
The 29-year-old scored 18 Serie A goals in the red and black shirt last season.
