The 19-year-old academy graduate has been patiently waiting in the wings for his chance and certainly grabbed it, putting in a wonderful display in defensive midfield.
Long was delighted for Reed, who he jokes is like the lead character of American TV show 'Ray Donovan' - a professional 'fixer' who makes people's problems disappear.
"I call him Ray Donovan because he just cleans up in midfield, he said with a smile.
"I was delighted for him because he trains hard and I was really impressed since the first day I came in.
"He was waiting for his chance. It is hard to get a game with the quality we have in midfield, but two suspensions and Jack Cork injured as well, it has given him a chance to shine and he took it.
"I thought he was immense and did really, really well stopping the ball getting to the attack and breaking up play. It was good to watch."
