Nottingham Forest defender Nikola Milenkovic has hailed the "family atmosphere" created by Vitor Pereira and his coaching staff. Pereira has won eight and lost just four of his 16 matches in charge in all competitions since replacing Sean Dyche in mid-February, and is currently overseeing a 10-game unbeaten run - Forest's longest for a decade. "For sure this season has been turbulent for us," Milenkovic told media before Thursday's Europa league semi-final second leg against Aston Villa.
