Porto striker Silvestre Varela has welcomed interest from West Ham United.
Porto value Varela at £6.5million and are determined to hold out for the full amount, after he underlined his goal threat by scoring twice in a 4-2 pre-season win over Venezuela's Deportivo Anzoategui in Puerto la Cruz on Sunday.
He said: "To be linked with a club who value me is a good sign. It is pleasing to hear that."
