The winger has been linked with a return to AC Milan.
"Personally I have to help Watford to go out of the bottom of the table and all the players we have to make an effort for this. For a player, I'm proud to listen to all of these offers, like last year, this year, but my focus is here, in Watford and I'm really happy.
"Every training, every game here in Watford is different than other teams what I have been because it's a different style and the game is more direct and we don't have the ball possession too much. I have to adapt myself in Watford and that's what I'm doing last season and this season, so I'm really good - last season was I think the first in my career scoring 12 goals, I think it's a lot and I'm happy here and I have to adapt myself to that shape and that style."
