Elliot Simoes has swapped Broadhurst Park for Oakwell - securing a move to League One Barnsley for an undisclosed fee.
The 19-year-old came through the ranks at the Rebels before making his senior debut in April, eventually going on to make 23 appearances for the first team.
Speaking in his first interview with the Tykes' website, Simoes had this to say: "I wasn't expecting it to happen. I was surprised, I was heading to FC United training as normal, then I got a call telling me that Barnsley wanted to sign me.
"It's probably the best thing that's happened in my life. I knew I wanted to come straight away, I knew I wanted to join.
"The only worry you ever have is meeting new people and leaving home, but everyone has been great with me so far. I can't wait to get playing now."
