Nottingham has definitely made this season more interesting. Team that was once thought to be weak has become strong competitor taking third place with good lead over team in fourth place. This means that real competition will likely be for fourth place while top three teams seem safe. Sports league is more exciting when many teams are competing for championship until end. Sadly this season Premier League has been dominated by Liverpool which is different from last season. Last season Arsenal and Manchester City had thrilling competition for top two spots constantly overtaking each other. In the end Arsenal did not win but excitement lasted until end.
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.
