Although the match was scheduled as a home game for Blues, it was switched to Forest’s training ground because of a waterlogged pitch at Wast Hills.
Blues struggled to cope with the pace and power of Forest in the early stages and the hosts deservedly took the lead just before the half-hour mark.
However, Blues rallied and were back level just five minutes later when Sam Deadfield’s shot was deflected past the Forest keeper.
The improvement continued after the break and Kyle McFarlane (pictured) struck his seventh goal of the season with 53 minutes played to secure the win for Steve Spooner’s side.
"We were on the back foot for the first 20-25 minutes and Forest were too quick and powerful for us," admitted Academy coach Spooner.
"Tactically we were a little naïve as well and they deservedly took the lead. But once we managed to get the information onto the players about a few little tactical changes we started to get more of a grip on the game.
"We were more creative and we managed to get back in it by scoring a goal through Sam Deadfield. There was some good play down the left before the ball got to Sam who struck it well and it deflected in off a defender.
"In the second-half Forest came at us again but we defended well all the way back to front and kept our shape.
"For the goal Kyle skipped past defender on the right, accelerated away from him and calmly finished in bottom corner. He's on fire at the moment and scoring a few goals."
