Forest fielded a young looking side whilst the Blues starting XI included trialist Darcy Blake and a welcome return for defender James Fry following injury.
Hooper’s side raced out the traps and were ahead after just three minutes. An incisive break away run from Koby Arthur resulted in him sliding in Allan down the left hand channel who then cleverly pulled the ball back for Deadfield allowing him to rifle the ball into the top left hand corner.
With Blues dominating possession, a number of chances came their way to double the lead. Kyle McFarlane gambled on a loose ball to only see Forest keeper Ross Durrant smother from his feet.
The Forest keeper was soon tested again as he palmed away a ferocious strike from Arthur from the edge of the box.
With Blues looking comfortable, a collapse in concentration from midfielder Liam Truslove allowed Blues’ counterparts to draw level.
Forest midfielder Stephen McLaughlin snatched the ball away from Truslove on the edge of the box and then fired the ball low into the bottom left hand corner despite the best efforts from Blues keeper Connal Trueman.
The Forest equaliser seemed to affect Blues and it was the East Midlands side that began to control proceedings up until the half time break.
Soon after the equaliser, Trueman made a superb point blank save from Walker to keep the scores level.
The Blues keeper then made two superb saves from Walker and McLaughlin to keep the scores level going into the break.
The half time break seemed to rejuvenate Blues, with Allan beginning to control the game in midfield.
It was from an Allan corner just two minutes into the second half which saw a Truslove header rattle the crossbar.
The attacking intent from Blues was there for all to see and it was the Scotsman Allan who restored his side’s lead. Some good build up play in the Blues midfield allowed Allan to have time and space on the edge of the Forest box and within a flash his low left footed drive whistled past Durrant low into the bottom right hand corner.
Allan was soon threatening again as his clever run through midfield resulted in him firing a shot at goal to only then see it bounce off the crossbar.
After that scare and as the game entered the final third, Forest midfielder Kieran Wallace fired a shot just wide of Truman’s right hand post but this marked the only real threat from the away side as the game slowly began to fizzle out.
With the hosts continuing to look impressive at the back nothing was going to break them down and that’s how the game went, leaving Blues to run out deserved 2-1 winners.
"I felt we deserved the victory for how well we did defensively and on the amount of chances we created at the other end," said Hooper.
"We took everything we'd dome in the previous game in terms of the hard work and endeavour and married that with quick passing play and quick movement off the ball. That allowed us to create a lot more opportunities, but also to remain defensively strong at the back. In the periods of the game when Forest were on top, we stood up strong to what they threw at us."
