Nottingham Forest can be considered as nearly nothing before this season because after promoting up to Premier League two seasons ago, they finished previous two seasons with postions from 16 to 17, that are surely not impressive ranks and only enough for them to seal the appearance in Premier League this season.
What they have done so far in Premier League this season are out of all expectation even their own expectation before this season start. Anyway the season is about remaining one-third of its length till its ending and Nottingham Forest actually have a good position and enough advantage to seal their appearance in top four or at least top five of Premier League. With highly chance of Premier League to have five slots for UEFA Champions League next season, Nottingham Forest have a perfect opportunity to participate in Champions League after several decades.

At the moment forest is just four points behind Arsenal who is at second position. Still nine more games to go and if Nottingham Forest maintain there current record in upcoming matches then they have the opportunity to play Champions league. Lots of games still to be played in EPL, that's why Forest must not relax at this critical stage of the league.
