Napoli's Eduardo Vargas insists he is not aware of any agreement with Valencia about a move to Spain.
The Chilean forward struggled to settle in Italy after moving to Napoli in January 2012 and returned to South America on a short-term deal with Gremio.
The striker's agent has stated that a bid from Valencia has been lodged with Napoli and claimed that the two clubs are discussing terms.
However, the 24-year-old is in the dark about the proposed switch, although he would welcome a new start in Spain.
In comments reported by El Grafico Chile, Vargas is quoted as saying: "Nobody has told me anything but I hope that does happen."
