He told BBC Sport: "I'm not disappointed the important thing is to get more playing time and prepare myself for the upcoming challenges.
"It could be anywhere at Watford or elsewhere. I'm looking forward to playing in the premier league in the coming year - it is a dream come true to sign for a Premier League club."
"I had a great experience at Granada and I think that can help me this season," he added.
"The language and the way of football is the same so am hoping to make use of this opportunity to add more experience and maturity to my game."
