Crystal Palace have signed teenage winger Randall Williams from non-League side Tower Hamlets.
The 19-year-old has earned a short-term deal until the end of the season after impressing on trial with the Eagles.
Williams told the club website: "[Palace manager] Alan Pardew said he wanted to have a look at me so he brought me in to train with the first team.
"I played in a behind-closed-doors friendly against Crawley Town, and did well there and he liked me.
"I like to drive at players, and I'm a quick dribbler. There's areas that I need to work on but that's why I'm here. I just want to better myself and to go up nine leagues is a big step so hopefully the team and everyone around the club can help me improve."
Palace have the option to extend Williams's contract at the end of the season if they wish.
