The winger has declared he wants to leave parent club Barcelona this summer, though isn't sure about re-signing for the Hornets.
He told Sport: "In the summer I will leave Barça but I do not know where I will go. We'll see. I have to rest and I have to decide, but of course Watford is an option, why not?
"The coach (Javi Gracia) wants me to stay, but I have to see, go slowly and analyse it well. Let's see what happens with my representative.
"We are currently calm.
"I'm happy with the experience I've had here and I'm happy with the months at Watford."
