Both Cavani and his Uruguay teammate Luis Suarez have been linked with moves away from PSG and Liverpool respectively, and the 27-year-old said that he can't be sure know what the future holds.
"Luis Suarez and I are already at great clubs," Le 10 Sport quotes Cavani as saying. "We belong to teams that are among the best in the world. I think we defend the colours of our club with pride and prestige.
"But in football, you never know, anything can happen. One day you're in one team and the next you can be in another."
Cavani has scored 22 goals in 63 appearances for Uruguay.
