Former Crystal Palace winger Randell Williams has completed his move to Watford.
The youngster was released by Palace at the end of May.
"The next step for me is first team football, it's a massive step. Watford produced around six debuts last season, I think," said Williams.
"So the opportunity here, hopefully it stays high. I know at Palace not many boys had their chance to have their debut, but here hopefully I can get a chance.
"It is a new start for everyone with the new manager coming in (Marco Silva), he doesn't know everyone so it's a big opportunity and it will be good to impress him.
"If I go out on loan, I hope to go to a Football League club. If not then I'll go out and do what I need to do, just gain that bit of senior experience."
