Deulofeu says he's happy with his work this season at Watford, but won't rule out moving to a bigger stage.
He told Esports Cope: "I do not know what will happen in the future. Watford at the moment is not a top team, but is growing.
"As a player I always think big.
"I do not know, what I can say will be the best for me - Spain, Italy and the Premier are very big leagues."
Asked about a return to Barcelona, Deulofeu added: "I have returned many times and it did not work. I must go my way. I will not return."
