The winger, who played a pre-season friendly for Liverpool aged just 15 in the summer of 2010, became the club's third-youngest player and looked lively in the brief period he was on the pitch.

You just need to draw your horses back a bit," said the Scot.
"He wouldn't have been there if we weren't in the position we were in
"It is nice to see the kids get a game but it is also better for us to look after them and manage them.
"We are not going to throw kids in and destroy them, but it is nice to see them on the pitch,
so basically i wouldnt get any hopes up of seeing raheem much more this season, if any
even tho he looked twice the player than anybody we have on the wings
