I believe the game between Chelsea and Nottingham Forest will be interesting because both teams are in the race for top 4 position. Both teams occupy 4th and 5th positions in the league table with the same points so they will both want the three points to move up the table. Personally I feel Nottingham Forest can get this three points from this game.
How competitive the Nottingham Forest vs Chelsea match will be will depend on the performance of these two teams in the next two matches. In the next two matches, Nottingham Forest will play against Leicester and West Ham. And Chelsea will play against Newcastle and Manchester United. If Nottingham Forest's performance is somewhat stable, they will get easy wins in the next two matches. However, Chelsea's opponents are very strong in both matches. Even winning 2 matches out of the last three matches is quite difficult for Chelsea now. So, I will not be surprised if we see a comeback of Nottingham Forest in the last moment of the season. Even I am waiting to see a comeback of Nottingham Forest. This team may qualify for the Champions League.
