Nottingham Forest midfielder Lewis O'Brien has enjoyed playing for Manchester United great Wayne Rooney.
O'Brien is on-loan at Rooney's DC United.
He told DC United's official website: "It's massive, if you look back at my career I've played against him a few times as well.
"We've had a few jokes about it. I know people that he's managed previously back at Derby and stuff and it's a perfect opportunity for me.
"He played in a similar position that I play in and I think he's going to make everyone he coaches a much better footballer."
