Swansea City are ahead of Lazio in the race for West Ham striker Enner Valencia.
Italian transfer expert Gianluca Di Marzio says Lazio risk missing out on Valencia as they've been outbid by Swansea.
Francesco Guidolin's club have offered €10m plus €3m in add-ons to take the Ecuador international.
The striker was a named target for the Biancocelesti over the summer, before and after Marcelo Bielsa's hasty exit.
